2020-11-30 David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-11-26 David Anderson
    * print_debug_gnu.c: In current compilers the blocks
      have a CU offset to the skeleton DIEs (when
      is split dwarf) so we print some data on
      each CU DIE now.
2020-11-25 David Anderson
    * Makefile.in: Regenerated from configure.ac.
      To support data needed for dwarfexample make check.
2020-11-25: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-11-23: David Anderson
    * CMakeLists.txt: now -D-DDWARF_WITH_LIBELF=OFF works
2020-11-23: David Anderson
    * glflags.h, glflags.c: Added field glflags.gf_max_space_indent
      with value 10 so that really deep TAG nesting does not
      result in mostly blank thousand-character lines. 
      If there is a call for it, the value could be supplied
      by a new dwarfdump option.
    * globals.h: Removed two functions defined and 
      only used in print_die.c.
    * print_die.c: Too deep nesting is unreadable so now
      when 10 or more deep the output uses for example ...100...
      instead of hundreds of spaces to indicate depth.      
      Indentation of DW_OP output changed in some cases.
2020-11-22: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-11-22: David Anderson
    * print_frames.c: The refactoring left old dealloc
      in place that are no longer appropriate.  Removed them.
    * print_die.c: DW_FORM_exprloc was, when printing FORMs,
      printing the FORM later than desired. Now shows
      up in the right place.
2020-11-22: David Anderson
    * print_die.c: When an attribute expression DW_OP is
      a DWARF5 reference to a DW_TAG the details of the
      reference are indented a little and printed on
      the line after the DW_OP itself. 
      Seems easier to read that way.
2020-11-22: David Anderson
    * command_options.c: The option is now
      --format-expr-ops-joined
    * dwarfdump.1,dwarfdump.conf,testdwarfdump.conf: Reflects
      the new option.
    * dwconf.c,glflags.c,glflags.h: Reflects the new option.
    * print_die.c: Reflects the new option.
2020-11-21: David Anderson
    * dwconf.c: Error message needed a slight wording change
      when we discover the abi requested does not exist.
2020-11-21: David Anderson
    * command_options.c: Added a new option, but it will be
      removed shortly as not needed.
    * dwconf.c: Clarified the code with a more complete
      set of return values.
    * dwconf.h: Macro defines for the new return values.
    * print_die.c: Now allows printing expression operations
      one per line. Which will be the default very soon. 
2020-11-21: David Anderson
    * print_frames.c: Error message improvements and
      refactored fde/cie printing to make it easier
      to follow.  Now if fde printing errors-out
      we continue on to attempting to print cies.
2020-11-20: David Anderson
    * print_frames.c: A better indent for expression ops
      from frames. More detailed error message too.
2020-11-17: David Anderson
    * command_options.c: Minor line shortening.
    * dwconf.c: Previous commit introduced a few bugs.
      Fixed, and clearer now. 
2020-11-16: David Anderson
    * command_options.c: Now accepts --format-expr-op-per-line
    * dwarfdump.1: Mentions the option.
    * dwarfdump.c: Small changes passing die_indent_level
      around so formatting looks sensible with the new option.
    * dwconf.c: Now deals with 
      option:  --format-expr-op-per-line
      in dwarfdump.conf. the option: command must preceed every
      beginabi: command.
    * esb_using_functions.h: Adding die_indent level to another
      function prototype.
    * glflags.c,glflags.h: Renamed the flag for the option to 
      gf_expr_op_per_line.
    * print_die.c,print_frames.c,print_frames.h,
      print_hipc_lopc_attr.c,print_locs.c: Now passing
      die_indent_level anywhere needed.
2020-11-15: David Anderson
    * testdwarfdump.conf: A special version to test
      the 'option:' command.
2020-11-15: David Anderson
    * esb_using_functions.h: Add Dwarf_Die arg to
      dwarfdump_print_location_operations().
    * glflags.h, glflags.c: Adding gf_multi_line_expr. Not used yet.
    * globals.h: Adding Dwarf_Die to check_die_expr_op_basic_data().
    * print_die.c: Now printing references to DIEs in
      DWARF expressions.
    * print_frames.c,print_frames.h,print_locs.c: Adding Dwarf_Die
      to arg lists. Some reformatting to libdwarf coding style.
2020-11-12: David Anderson
    * dwarfdump.1: Clarified the role of the --verbose
      option and corrected spelling and formatting errors.
    * print_lines.c: Revised one glflags.verbose test so it
      reads the same way as other verbose tests. Fixed
      various lines to meet the libdwarf coding style.
    * tag_attr.c,tag_tree.c: Changed to meet the
      libdwarf coding style. 
2020-11-11: David Anderson
    * print_abbrevs.c: Fixing a mistake in the
      new code. The error lead to an
      erroneous  error being reported
      in objects where the compiler left off the final
      zero in the .debug_abbrev section.
2020-11-09: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-11-08: David Anderson
    * globals.h: Declaring new function print_all_abbrevs_for_cu()
    * print_abbrevs.c: Refactored to allow printing abbrevs
      for a single CU and/or all abbreves at once.
    * print_die.c: If -vvvv and printing .debug_info/.debug_types
      print the abbrev section applying to each CU reported.
      If checking (as with -ka) check for errors in
      the abbrevs of each CU (no -v required for checking).
2020-11-05: David Anderson
    * dwarf_tsearchbal.c,dwarfdump.c,print_lines.c,tag_attr.c:
      These had some #include not protected by the HAVE_*H
      config.h (and cmake) provide. Fixed.
    * testobjLE32PE.base: baseline update to match current
      output.

2020-11-04: David Anderson
    * globals.h,print_lines.c,print_die.c: Adding arguments for a 
      srcfiles array for the CU to
      to print_line_numbers_this_cu(). Now, with -vvv
      just printing line tables will print the dwarf_srcfiles
      array of strings.
2020-11-03: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-11-03: David Anderson
    * Makefile.am, CMakeLists.txt: print_macros.c renamed
      to print_macinfo.c for clarity in naming.
    * Makefile.in: Regenerated.
    * globals.h: Added Dwarf_Die argument to
      print_macinfo_by_offset().
      Added srccfiles, count argument to
      print_macros_5style_this_cu().
    * print_die.c: Renamed macro_check_cu() to
      print_macinfo_for_cu() for clarity in naming.
      print_macinfo_for_cu() now prints the file name
      (from srcfiles list) if it is DW_MACINFO_start_file.
    * print_macinfo.c: Nowuses passed-in srcfiles
      to get the full path for the file index 
      DW_MACINFO_start_file.
    * print_macro.c: Prints the DWARF5 set_file macro
      correctly with name.
    * runtests.sh: 'make check' baselines made a bit
      larger and added -vvv to the dwarfdump command
      generating those baselines.
    * test-mach-o-32.base,testobjLE32PE.base,
      testobjLE32PE.base,testuriLE64ELf.base: New baselines
      with additional content per CU and more lines.
2020-11-01: David Anderson
    * print_die.c: With -vvv dwarfdump now prints
      the array dwarf_srcfiles generates so library
      users can compare the compilation unit, its
      line table header, and what dwarf_srcfile()
      provides. DW_AT_decl_file and DW_AT_call_file
      now result (in printing attributes) in the right
      source file printing.
2020-10-30: David Anderson
    * esb.c,esb.h,uri.c: Removed trailing whitespace,
      shortened a few lines.
2020-10-29: David Anderson
    * command_options.c,print_die.c: Fix indents, remove
      trailing whitespace.
    * In this ChangeLog some of the August lines
      had tabs and the lines were kind of messed up.
      Fixed.
2020-10-29: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-10-29: David Anderson
    * print_die.c: Factored out the indent-spaces code
      into static function print_indent_prefix().
      For now there is no change in output format,
      though for large indents (greater than around 6)
      the spacing gets so large the output becomes
      unreadable.
2020-10-28: David Anderson
    * print_die.c: Dwarfbug DW202010-002. In case of
      a circular DIE tree memory outside of the target
      DIE stack array would be written to and
      referenced.  Now we test at all the places
      the stack index is incremented and print
      a useful error message.
    * print_section_groups.c: #if 0 code updating
      glftab as the table data has never been used.
2020-10-22: David Anderson
    * command_options.c,dwarfdump.1: The man
      page and the -h (help) output spelled the long-form
      option for seeing Elf Section Group DWARF data
      incorrectly as --format-group=<n> but the real option
      has always been --format-group-number=<n> .  To see
      any section groups and the number libdwarf assigns
      to them do dwarfdump -i -vv <object name> Most object
      will have just section group 1 and dwarfdump/libdwarf
      handle that automatically. Groupnumber support was
      added in May 2017. See dwarf_init_path() page 34
      and Section 6.3 Page 46 in libdwarf2.1.pdf .
2020-10-20: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
    * glflags.c: see TRIVIAL_NAMING, used when doing
      scripts/buildstandardsource.sh
2020-10-19: David Anderson
    * dwarfdump.1: Document --format-suppress-sanitize
      Added documentation on --format-suppress-uri too.
      Reorganized the URI sections for greater clarity.
    * command_options.c: show --format-suppress-sanitize
      thus mentioning the option. If there are corruptions
      or bad string data in an object this can be dangerous
      to your terminal window.
    * esb.c: Remove #if 0 and the code for a function
      that was not a good idea: esb_constructor_rigid().
    * glflags.c: Adding glflags.gf_no_sanitize_strings
      initializer (used to use a global not in glflags).
    * glflags.c: Adding boolean gf_no_sanitize_strings
      declaration.
    * print_frames.c(print_location_operations): Remove
      unwanted code #if 0 through #endif
    * print_macro.c(print_macros_5style_this_cu): #if 0
      code removed. So deleted duplicate die printing
      calls.
    * print_pubnames.c: deal_with_name_offset_err()
      has not been used in a long time. Deleted.
    * sanitized.c(sanitized): add includes to allow
      glflags.h
      and use glflags.gf_no_sanitize_strings for checking
      whether to sanitize.
2020-10-19: David Anderson
    * dwarfdump.c,getopttest.c,print_lines.c,
      testobjLE32PE.test.c: Fixed indents and
      removed trailing whitespace.
2020-10-19: David Anderson
    * *.c *.h: No license terms changed but nearly
      all the copyright notices are now reformatted to
      line lengths appropriate for dwarfdump.
2020-10-18: David Anderson
    * tag_attr.list: Added standard tag-attribute
    relationships
      that are being used now.
    * tag_tree.list: Added standard tag-tag relationships
      that are being used now.
    * dwarfdump-ta-table.h: Regenerated.  
    * dwarfdump-tt-table.h: Regenerated.
2020-10-17: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-10-15: David Anderson
    * print_lines.c(print_line_context_record): Fixed the
      comments about DWARF4 vs 5.
2020-10-13: David Anderson
    * print_macro.c: Added the required check for 0
      opcode and print appropriately (it's the null byte
      at end of macro operands).
2020-10-12: David Anderson
    * dwarfdump.c: Now printf callbacks from libdwarf
      are sanitized() to prevent corrupted line data from
      compromising user terminal settings.
    * print_lines.c: Accomodation of DWARF5 in more places.
2020-10-11: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-10-11: David Anderson
    * command_options.c: Refined a wordy comment.  
    * dwarfdump.1: Document the new ability to
      get to GNU debuglink files automatically.
    * dwarfdump.c: Implement support for reading GNU
      debuglink and use it to find the target object.
2020-10-05: David Anderson
    * command_options.c: Implemented first part of
      making GNU debuglink options work.
    * dwarfdump.c: Now using dwarf_init_path()
      working toward making GNU debuglink options work.
    * glflags.h: Commented gf_debug_names_flag
      to avoid confusing it with debuglink.
2020-10-03: David Anderson
    * Makefile.in: Autoreconf using Ubuntu 20.04
      made small changes.
    * COPYING: Corrected the references to the BSD
      copyright
      to use "two-clause BSD license".
2020-10-02: David Anderson
    * command_options.c,glflags.h,print_frames.c: Remove
      trailing whitespace.
2020-10-02: David Anderson
    * command_options.c: New options --no-follow-debuglink
      and --add-debuglink_path=<text> for working with
      GNU debuglink.
    * glflags.h: Added gf_no_follow_debuglink and
      gf_global_debuglink_paths and
      gf_global_debuglink_count.
2020-09-30: David Anderson
    * command_options.c: If more than one non-dash
      word is at the end of the dwarfdump command it used
      to complain no object name given.  Now in that case
      it complains that more than one was given. Slightly
      more sensible.
2020-09-27: David Anderson
    * dwarfdump.c: --print-gnu_debuglink output wording
      made clearer.
2020-09-27: David Anderson
    * dwarfdump.c: Now --print-gnu_debuglink also
      indicates what files it found in the paths
      calculated, making --print-gnu_debuglink more useful.
    * command_options.c: Corrected a typo in a comment
      about
      the option --print-gnu_debuglink.
2020-09-26: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-09-18: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-09-18: David Anderson
    * print_frames.c: Shortened too-long comment lines.
2020-09-17: David Anderson
    * print_frames.c: A very old typgraphical error
      meant that in rare circumstances memory leakage
      of a few bytes was possible with option
      --suppress-de-alloc-tree.
2020-09-10: David Anderson
    * esb_using_functions.h: Adding new argument to
      the print_ranges_list_to_extra() prototype.
    * print_die.c: Using that new argument to
      pass the true offset to the printing code.
    * print_ranges.c: Updated the printing to make it
    clearer
      it clearer the .debug_ranges offset is using a base
      address (when there is one).
2020-09-10: David Anderson
    * dwarfdump.c: Remove trailing whitespace.
2020-09-08: David Anderson
    * dwarfdump.c: Now cleans up terminating DW_DLV_ERROR
      allocation even when the object cannot finish
      dwarf_init*().  Fixes print_error() so it works
      right with dbg null.
2020-09-08: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-09-07: David Anderson
    * glflags.h,print_die.c: Fixed idents and trailing
      whitespace.
2020-09-06: David Anderson
    * globals.h:  print_die_and_children() declaration
      removed, the function is now static in print_die.c.
    * print_die.c: On an error following a call to
      dwarf_child
      (but where dwarf_child() succeeded) we were failing
      to dwarf_dealloc_die(child). And even the main path
      (no error from dwarf_child) failed to dealloc child.
2020-09-05: David Anderson
    * print_die.c: In a couple error messages spell the
      function name that returned error correctly.
2020-08-28: David Anderson
    * print_die.c: Fixed indent and trailing whitespace.
2020-08-27: David Anderson
    * dwarfdump.c: Fix some warnings counted as errors
      by ensuring the ERROR string is in them (they just
      flag in particular situations that the DW_AT_producer
      attribute is missing on the Compilation Unit).
    * print_die.c: Fix places where we double-counted
      errors.
    * print_frames.c: Annotate an existing ERROR so that
      it is counted in the ERROR count.
    * print_llex_codes.c, print_origloclist_codes.c,
      print_ranges.c,print_reloc.c: Fix double-counts
      of errors.
    * print_reloc_decls.h: Just do a printf, no reason
      to use struct esb_s here.
2020-08-23: David Anderson
    * compiler_info.c: Now we apply sanitized() to all
      the printed strings (just in case an object file is
      corrupted or maybe not plain ascii strings).
2020-08-23: David Anderson
    * dwarfdump-ta-ext-table.h: Regenerated 
    * tag_attr_ext.list: Added DW_AT_GNU_macros
      to the known-extensions list.
2020-08-23: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.
2020-08-23: David Anderson
    * checkutil.c,dwarfdump.c,print_die.c: Removed trailing
      whitespace, fixed indents.
2020-08-23: David Anderson
    * checkutil.c: Removed #if 0 lines from previous
      commit.  
    * dwarfdump.c: Removed debug printf lines.
    * print_die.c: Removed debug printf lines.
2020-08-22: David Anderson
    * checkutil.c: Temporary debug printf.  
    * dwarfdump.c: Revised pRangesInfo reset
      when we have a tied dbg, as in that case we often
      miss function/scope address ranges.  Temporary debug
      printf too.
    * globals.h: Adding a Dwarf_Debug argument to
      tag_specific_checks_setup() for when tied file
      present.
    * print_abbreves.c: Temporary debug.
      New arglist for tag_specific_checks_setup()
    * print_die.c: Get the text section bounds
      set (from tied object, if any) so checks of address
      will not incorrectly fail.
2020-08-22: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Regenerated with latest
      version string.

      yesterdays name was excessively long. New name is
      dd_get_integer_and_name().
    * print_hipc_lopc_attr.c: That name changed here too.
      and a blob of code was factored out into a new
      function update_cu_base_addresses() which just
      establishes names used in presenting details in
      case of errors (a function with no side effects but
      setting the glflags fields for use in error reports).
2020-07-15: David Anderson
    * CMakeLists.txt,Makefile.am: Added print_hipc_lopc_attr.c.

      argument.
      Added DW_TAG_skeleton_unit to the if condition.
      This function affects only whether a CHECK message

      does not yet do anything useful.
2020-07-01: David Anderson
    * esb.h: Make debug-only locals unsigned long instead
    of long.  * print_die.c: Where there is a N iteration
    loop adding
      to esb strings use N and an estimate of per-loop text
      size request a sensible space increment to ensure
      there is enough space  that completing the set of
      strings will not need another malloc.  Saved about 1%
      of cputime in full regression test.
2020-06-29: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,

      dwarfdump-tt-table.h: Regenerated.
2020-06-26: David Anderson
    * print_die.c (print_attribute): Increased the stack
      alloc of a string so that even fairly long
      loclists/rangelists won't require malloc.  A tiny
      indent and trailing whitespace instance fixed too.

      passes again.
2020-06-25: David Anderson

    Removed dead code. Corrected printing
      if rnglists, ranges, loclists locations. Corrected
      handling of the output with -k detected an error.
      Ensured a couple esb_s variables get destructed
      in case of error.  Added explanation how the
      print_attribute() code actually works.
    * print_frames.c: Corrected handling location
    operations
      when checking (-k options).

      dwarfdump-tt-table.h: regenerated
    * dwarfdump.c: Doing a slightly better job identifying
      the true range of text addresses in the object file,
      which matters for some -k (checking) options.
    * globals.h: Revised some argument lists for nicer
      reporting of errors found with -k options.
    * naming.c: regenerated.  * print_die.c: Certain names
      revised for greater
      clarity of intent. print_information ->

      common extentions 
    * tag_common.h: Incremeneted
      EXT_ATTR_TABLE_ROWS 16
      so the tables can be rebuilt.
2020-06-22: David Anderson
    * dwarfdump.c: Fixing some old formatting mistakes.
      NOT TO BE USED Yet.
2020-06-20: David Anderson
    * tag_attr.c,tag_attr.list,tag_common.h: Adding in
      DWARF5 TAG ATTR combinations required raising hard
      coded value, and improving one of the error messages
      appearing with the wrong limit.
2020-06-20: David Anderson
    * tag_attr.list: Added DW_AT_loclists_base,
      DW_AT_alignment,DW_AT_call_all_calls,DW_AT_noreturn
      with the TAGs they go with.
2020-06-17: David Anderson
    * Makefile.am, CMakeLists.txt: Renamed
      print_loclist_original.c -> print_origloclist_codes.c
      so the three distinct format loclist printers all
      end in codes.c.
    * Makefile.in: Regenerated
2020-06-17: David Anderson
    * print_loclists.c: Improve the formatting
      of the raw report.
    * print_rnglists.c: Significatly improve
      the formatting of the raw report.
2020-06-17: David Anderson
    * globals.h: Some args now just values, not pointers,
      the Dwarf_Addr * hipc in print_llex_linecodes()
      was a holdover from past versions. Not needed.
    * print_die.c,print_llex_codes.c,print_loclist_original.c,
      print_loclists_codes.c: Similarly.
2020-06-12: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h : updated version string.

      (temporary) filenames
      so it is easier to understand where to copy the new
      baseline result to update the right baseline.
    * testobjLE32PE.base: New baseline, needed as loclist
      output changed.
    * print_frames.c: Calling loclist dealloc on
      error to avoid leaks.
2020-06-10: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,

      dwarfdump-tt-table.h : Updated  version string
2020-06-09: David Anderson
    * Makefile.am: New files due to refactoring.  
    * Makefile.in: Regenerated.  
    * command_options.c: Added --print-raw-loclists
      which prints all the details of .debug_lists but does
      not do any reference to .debug_info or .debug_addr
      (for example).
    * dwarfdump.c: Deals with --print-raw-loclists by
      calling new function print_raw_all_loclists()
    * esb_using_functions.c: Minor change to support
      revised internal function interface to
      dwarfdump_print_location_operations().
    * glflags.h: Added global flag gf_print_raw_loclists.
    * globals.h: Several new interfaces added so
      dwarf_loc.c and dwarf_loclists.c call each other
      as needed. And support for the different loclists
      supported: DWARF 3, GNU Dwarf4 dwo extension,
      and DWARF5.
    * print_die.c:  Added die_indent_level a few places
      for loclist printing. Significant changes to support
      the loclist details.  Some renaming of things (data,
      functions) whose purpose was obfuscated by the name.
      Using new libdwarf interfaces that support the new
      data in libdwarf.  Some significat refactoring so the
      structure of what is being done can be easily seen.
      No longer computes final loclist low/high addr as
      libdwarf does that for us now.
    * print_frames.c: Reflects the revised function
      naming.
    * print_frames.h: Reflects the revised function name.
    * print_llex_codes.c: Factored out of print_die.c
      and heavily revised to reflect the new location data.
    * print_loclist_original.c: Factored out of print_die.c
      and heavily revised to reflect the new location data.
    * print_loclists.c: All new, this does the
    .debug_loclists
      specific printing.
    * print_loclists_codes.c: All new. Prints DWARF5
      loclists data properly.
    * print_locs.c: Reflects a revised function name.  *
    print_rnglists.c: Corrected an out of date comment.
    * uri.c: 'unsigned int' instead of 'unsigned' for a
      picky compiler.
2020-05-23: David Anderson
    * dwarf_globals.h: Define ESB_FIXED_ALLOC_SIZE 380.
    * print_die.c,print_lines.c,print_pubnames.c: Now using
      ESB_FIXED_ALLOC_SIZE in many places to (mostly)
      avoid any need for malloc/free by the esb functions.
2020-05-21: David Anderson
    * dwarfdump.c: Now using DROP_ERROR_INSTANCE macro
      everwhere needed, avoiding the hand-coding.
      Using dwarf_dealloc_attribute() now.
    * dwarf_globals.h: Extra parens in DROP_ERROR_INSTANCE
      for readability, and using dwarf_dealloc_error()
      in it for type-checking.
    * print_die.c: Using dwarf_dealloc_attribute()
      and dwarf_dealloc_die() now.
    * print_frames.c: Now we call DROP_ERROR_INSTANCE
      with the proper arguments as the compiler can
      type-check that sort of thing. And fixed code to
      honor its invariants (a function that should not
      return DW_DLV_ERROR now avoids doing so).
    * print_lines.c: Also using DROP_ERROR_INSTANCE now.
    * print_macro.c: Now using DROP_ERROR_INSTANCE
      and dwarf_dealloc_attribute().
2020-05-19: David Anderson
    * print_die.c: In an error case failed to dealloc the
    rnglists head.
2020-05-19: David Anderson
    * dwarf_names.c,dwarf_names.h,
    dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: New version string.
2020-05-19: David Anderson
    * print_die.c: Removed arguments that were not
    needed from
      a couple of libdwarf rnglists functions and changed
      code here to match.
    * print_rnglists.c:  Fix trailing whitespace.
      Turn on printing range lists and offset table entries
      (if any) with --print-raw-rnglists even if no -v.
2020-05-17: David Anderson
    * globals.h: Remove trailing whitespace.  *
    print_die.c: Now prints DWARF5 .debug_rnglists section.
      Fixes issues with handling certain attributes with
      new FORMs in DWARF5.
    * print_frames.c: Avoids terminating frame printing
    when
      errors are seen attempting to get a function name
      for an fde.
    * print_rnglists.c: New. Implements the details
    of reading
      the .debug_rnglists section.
    * dwarf_alloc.c: Added new type, DW_DLA_RNGLISTS_HEAD.
    * dwarf_die_deliv.c: Now reads all the DWARF5 CU
    DIE fields
      that are needed to evaluate FORMs and section
      references.
2020-05-04: David Anderson
    * print_rnglists.c: Completing the code to print
      all the details of the raw content of the DWARF5
      .debug_rnglists section.
2020-05-02: David Anderson
    * CMakeLists.txt: Added print_rnglists.c.  *

    Regenerated.  * command_options.c: Added a new option
    --print-raw-rnglists.  * dwarfdump.c: Implemented
    printing raw rangelists, but
      not yet completely.
    * gflags.c: Added a new flag gf_print_raw_rnglists.
    * print_rnglists.c: Prints an initial partial
      report on  contents of any .debug_rnglists[.dwo]
      section.
    * print_sections.h: Just minor reformatting of
      comments. No change.
2020-04-28: David Anderson
    * dwarfdump.c,print_die.c,print_frames.c: Removed
      the use of tab chars in the output and use a space or
      two instead. This greatly shortens the line length
      needed when printing frame information details.
      Looks better without the 16 or 24 leading blanks on
      all those lines too.  The tab characters elsewhere
      were removed long ago.
2020-04-26: David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: Updated version string.
2020-04-25: David Anderson
    * print_die.c: Fix indents and remove trailing
    whitespace.  * print_frames.c: Rearranged what was
    local Dwarf_Error
      and what was local. Fixed a dwarf_dealloc to say
      DW_DLA_ERROR, not DW_DLV_ERROR. Yikes.
    * print_lines.c: Changed a local variable name,
      filename->lsrc_filename so searches were more
      meaningful. Added missing dwarf_dealloc to clear
      dead data when appropriate.
2020-04-24  David Anderson
    * dwarf_names.c, dwarf_names.h: Updated version string.
    * dwarfdump-ta-ext-table.h,dwarfdump-ta-table.h,
      dwarfdump-tt-ext-table.h,dwarfdump-tt-table.h:
      Updated version string.
2020-04-23  David Anderson
    * print_aranges.c: Remove a debugging printf.
      Delete duplicate dealloc calls.
    * print_lines.c: clarify what the dealloc's do
      so we don't call dealloc on something already
      cleared.
2020-04-23  David Anderson
    * dwarfdump.c: Added in dealloc to prevent leaks.
    * print_aranges.c: More thorough doing dealloc
      as soon as appropriate.
    * print_die.c,print_frames.c,print_lines.c:  Doing
      appropriate early dealloc in the necessary places.
2020-04-22  David Anderson
    * command_options.c: Added to a stderr warning
    (longer message).  * dwarfdump.1: Removed SELECTIVE
    ENTRY PRINTING
      section in favor of the new URI-STYLE INPUT/OUTPUT
      and the SELECTIVE* data renamed as  LIMITING OUTPUT.
    * dwarfdump.c: Now everywhere expects to get back
    status
      from printing DWARF section data, reports on it if
      there as an error , and continues.
    * esb_using_functions.h: Various functions now have
      Dwarf_Error * arg and return a DW_DLV_* value.
    * globals.h: Now all the relevant functions return
      a DW_DLV_* value and require Dwarf_Error * argument.
    * print_aranges.c: Some formatting fixes plus
      now get_producer_name() returns a DW_DLV* value,
      like more or less everything else.
    * print_die.c: Major revision to now return on error
      with DW_DLV_* instead of printf followed by exit().
    * print_frames.c: New local function
    dealloc_loc_atlist()
      to clean up on-the-spot. Reintroduced
      load_CU_error_data() to amplify the information
      reported on error.
    * print_lines.c: Line formatting corrected.
    * print_macro.c: Line formatting corrected.
    * print_pubnames.c: Reflects new arglist to
      get_producer_name().  
    * print_ranges.c: Line
      formatting corrected.  
    * dwarf_errmsg_list.h: Added
      DW_DLE_USER_DECLARED_ERROR so
      dwarfdump can declare an error on its own.
    * dwarf_error.c: Added dwarf_error_creation() to
      allow dwarfdump
      to create an error with a detailed explanation.
    * dwarf_form.c: declared a DW_FORM_rnglistx to be
      used soon.
    * dwarf_ranges.c: Comments about the
      missing .debug_rnglists
      section support (coming soon).
2020-04-22  David Anderson
    * dwarfdump-ta-ext-table.h: regenerated 
    * tag_attr_ext.list: Added to common extensions list
      DW_AT_GNU_pubnames DW_AT_GNU_pubtypes
      DW_AT_GNU_dwo_name DW_AT_GNU_ranges_base
      DW_AT_GNU_addr_base
2020-04-17  David Anderson
    * dwarfdump.c: Clarified some error messages and
      changed the should_skip_this_cu() from a predicate
      function to one in the standard form returning
      a DW_DLV_* value with a boolean pointer and a
      Dwarf_Error*
    * globals.h: Now should_skip_this_cu and
      print_section_groups_data are in standard form for
      calling libdwarf functions, returning a DW_DLV*.
    * print_die.c, print_aranges.c, print_pubmames.c,
      print_ranges.c,print_section_groups.c: Now with the
      standard form returning a DW_DLV* and no longer call
      print_error so returns on error, does not exit().
      Also fixed a lack of a dealloc of cu_die2 in
      print_die.c.
    * print_macro.c: Deleted dwarf_dealloc() that are
      no longer appropriate given we don't just call
      exit(). These were not allocated by the function that
      was dealloc-ing so removed the deallocs here: Let
      higher levels do it when we return the DW_DLV_ERROR.
2020-04-16  David Anderson
    * globals.h:prototypes of print_line_numbers_this_cu
      and
      print_macros_5style_this_cu changed to the new style
      with int return and Dwarf_Error *argument.
    * dwarf_macrocheck.c: Added a comment line.  *
      print_die.c(print_one_die_section): Calls the
      revised section prints per-CU- so errors are passed
      back and dealt with.
    * print_lines.c: Now functions return int instead
      of print_error and exit. Various errors get more
      detailed output too.
    * print_macro.c: Now with the new style of returning
      errors up to caller.
2020-04-14  David Anderson
    * globals.h: Deleted unused function prototype.
      Updated print_macinfo_by_offset() to the new style
      of returning a DW_DLV*.
    * print_die.c: Now a couple of places we avoid
      calling print_error() as it exits and deal sensibly
      with return values.
    * print_macros.c: The printing of DWARF2,3,4 macro data
      is now updated to avoid print_error() and to print
      more details about problems.  And report output now
      looks more regular.
    * print_abbrevs.c: Fixed indents and trailing
    whitespace.
2020-04-13  David Anderson
    * dwarfdump.c,globals.h, print_abbrevs.c:
      print_abbrevs()
      now returns an error properly with the details so
      dwarfdump can deal with it properly.
2020-04-10  David Anderson
    * dwarfdump.c: Printing gdb_index and debugfission
      index
      code now all returns DW_DLV* in the new style.
    * globals.h: print_gdb_index() and
      print_debugfission_index()
      get updated prototypes.
    * print_debugfission.c: Code to match the new protypes,
      passig errors back up.  Revised formatting a bit
      for accuracy and completeness.
    * print_die.c: Eliminated the odd use of stderr. All
      now stdout.
    * print_gdbindex.c: Improved various error messages.
      Updated print_gdb_index() to the new return-on-error
      approach.
2020-04-07  David Anderson
    * compiler_info.c: Clarified a comment and
      split a too-long line.
    * dwarfdump.c: Now handles a print_pubnames that
      returns a DW_DLV* and deals with it. Made
      a dwarf_dealloc conditional on  a non-null
      cu_die_for_print_frames. get_producer_name()
      now always returns and avoids leaks.  We add
      DEBUG_PUBNAMES  to the list wh print CU data on error
      (It knows the CU-DIE)
    * gflags.c: Reformatted to avoid a too-long line.
    * globals.h: Revised prototype for print_pubnames().
    * print_aranges.c: Removed too early destructor
      on producer_name.
    * print_die.c: Fixed a too-long-comment-line.  *
    print_frames.c: Moved a check for DW_DLV_ERROR up
      a few lines so we don't check gf_check_frames()
      when not needed.
    * print_pubnames.c: Removed deal_with_name_offset_err()
      as not the right thing to do. Now print_pubnames
      accepts a Dwarf_Error * argument and always returns
      a DW_DLV* result.
2020-04-03  David Anderson
    * print_aranges.c: Fixed trailing whitespace and
    indents.
2020-04-03  David Anderson
    * dwarfdump.c: Now print_strings() and
    print_macro_statistics()
      take Dwarf_Error * as argument and return a DW_DLV*
      value.
    * globals.h: prototype of print_strings altered.  *
    macrocheck.c(print_macro_statistics): Using esb_s to
      more detailed messages and returning a DW_DLV*
      value..
    * macrocheck.h: Updated prototype for
    print_macro_statistics().  * print_frames.c: Deleted
    many #if 0/#endif and their
      debug printf-s.
    * print_strings.c: Now uses get_true_section_name() so
      we report on any compression used.
2020-04-03  David Anderson
    * runtests.sh: Added esb to the build of selfmc as
    macro check
      now uses esb.c. Made the dwarfdump tests mention
      of update 'mv' commands be conditional on having
      actually found a difference (having them show when
      no difference was pointlessly confusing).
2020-04-03  David Anderson
    * dwarfdump.c: print_aranges() now uses the new form
    and returns
      a DW_DLV_* value.
    * globals.h: print_aranges returns a value and has
    a Dwarf_Error*
      second argument now.
    * print_aranges.c: No longer calls print_error()
    but instead
      returns a DW_DLV to dwarfdump.c.
2020-04-03  David Anderson
    *
    dwarfdump.c,glflags.h,globals.h,print_die.c,print_frames.c,
      print_locs.c,print_reloc.c,print_reloc_decls.h,print_static_funcs.c:
      Fix indent errors and remove trailing whitespace.
2020-04-02  David Anderson
    * addrmap.c: Ensure it wn't try to use a null input to
    addr_map_destroy().  * dwarfdump.1: Add documentation
    on running dwarfdump on split-dwarf
      objects (See DWARF5 standard, section 6.3).
    * dwarfdump.c (process_one_file):Applyingthe new
    error-return scheme
      to dwarf_frames.c required serious revisions and
      refactoring.
    * dwconf_using_functions.h: The declaration of
    print_frames()
      changed.
    * glflags.h: gf_debug_addr_missing_search_by_address,
      gf_error_code_in_name_search_by_address, and
      gf_all_cus_seen_search_by_address are here now
      instead of being hard to reason about global/local
      data.
    * glflags.c: Initializes the three fields.
    * globals.h: Revised declaration of print_frames() and
      get_proc_name.  Removed the declaration of
      current_cu_die_for_print_frames.
    * print_die.c(print_attribute): Properly use the
    return value
      of dwarfdump function get_proc_name_by_die().
      Also renamed a small number of local variables
      in print_exprloc_content() to make the code more
      readable( tempud -> exprlength, tempud->fileindex);
    * print frames.c: Major revisions to clarify
      data lifetimes and to return DW_DLV_ERROR
      to let higher levels clean up for themselves.
      Stop returning true/false and return DW_DLV_OK or
      DW_DLV_NO_ENTRY with respect to finding procedure
      names from code addresses`.
    * print_locs.c: Added an accidentally-omitted
      esb_constructor for secname.`
    * print_ranges.c: Move acquiring section name down
      after the first call of dwarf_get_ranges() so we get
      the true name with any compression involed reported.
    * print_sections.c: Removed Dwarf_Die
    current_cu_die_for_print_frames,
      it is no longer needed.
    * print_reloc.c: Was failing to free locally allocated
      space in some places in print_relocinfo_32().
2020-03-30  David Anderson
    * dwarfdump.c,dwconf_using_functions.h,
      globals.h,print_die.c,print_frames.c,print_frames.h,
      print_locs.c: Applyingthe new error-return scheme
      to print_locs.c involves a number of changes beyond
      print_locs.c itself.
2020-03-29  David Anderson
    * dwarfdump.c: Change several section reports to the
      new approach of errors propagating back to dwarfdump
      process_one_file().
    * globals.h: print_debug_names(), print_object_header()
      print_relocinfo(),print_tag_attributes_usage()
      print_attributes_encoding() all now return status
      DW_DLV_OK etc as appropriate.
    * print_die.c(print_attributes_encoding,
      print_tag_attributes_usage): Implement passing status
      back to process_one_file().
    * print_dnames.c,print_reloc.c,print_reloc_decls.h:
      Implement passing status back to process_one_file().
2020-03-28  David Anderson
    * dwarfdump.c: print debuglink and print str_offsets
      now getting dwarf status and Dwarf_Error back.
    * dwarf_globals.h: Revised prototype for
      print_str_offsets_section().
    * print_str_offsets.c: Now returns libdwarf status
      and lets dwarfdump print the error if there is one.
2020-03-28  David Anderson
    * dwarfdump.c(process_one_file): Beginning a
      project to pass libdwarf status all the way back to
      dwarfdump.c. Enables more flexibility in printing
      and better ability to dealloc memory.
    * globals.h: print_static_funcs(), print_static_vars(),
      print_types(), and print_weaknames() now return int
      and pass in a Dwarf_Error.
    * print_static_funcs.c,print_static_vars.c,
      print_types.c, print_weaknames.c: Implement
      passing back (to dwarfdump.c) of libdwarf status
      and Dwarf_Error by returning as required when
      DW_DLV_ERROR encountered.
2020-03-27  David Anderson
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,
      dwarfdump-tt-table.h: regenerated with latest version
      date string.
2020-03-27  David Anderson
    * print_die.c: Cleaned trailing whitespace and an
      indent error.
2020-03-27  David Anderson
    * print_die.c: Now does a better job of cleaning
      up libdwarf data it requested when there is a serious
      DWARF error.
2020-03-26  David Anderson
    * print_ranges.c: For a particular serious
    error/corruption
      print a detailed error message, dwarf_dealloc() the
      Dwarf_Error instance and skip to the next section
      to continue.
2020-03-26  David Anderson
    * dwarfdump.c: Now calls the new free_all_dwconf()
      to avoid leaking memory. should_skip_this_cu()
      ensures it does not leak.
    * dwconf.c: Use struct esb to build a string, avoid
      leaving a static string pointer around.
      Add free_all_dwconf() so the dwconf malloc space
      can be cleaned up at end of run.
    * dwconf.h: Declare free_all_dwconf().  *
    print_frames.c(get_proc_name): Add loopok variable so
    the loop
      on cu contexts can stop early when a serious error
      is encountered. The procedure name is not very
      critical, just nice to have.  Ensured no leaks in
      dwarfdump here.
    * print_lines.c: When an error but we wish to continue
      ensure the Dwarf_Error is dealloc-d.
    * print_pubnames.c: Ensure no leaks on error from
    libdwarf.
2020-03-25  David Anderson
    * print_die.c,print_lines.c,print_pubnames.c:
      Fix indents and remove trailing whitespace.
    * print_frames.c : Fix whitespace and ensure
      a return of DW_DLV_ERROR (which will basically be
      ignored anyway) gets a dwarf_dealloc applied to the
      Dwarf_Error argument.
2020-03-24  David Anderson
    * print_lines.c: Added a dwarf_dealloc DW DLA STRING
      that had been overlooked.
2020-03-24  David Anderson
    * print_die.c: Ensuring that when an error is
      created it gets dealloc-d.
    * print_gdbindex.c(print_gdb_index): It was failing
    to dealloc
      the data it requested from libdwarf.
2020-03-23  David Anderson
    * print_die.c: More cases trying to continue after
    error.
      And ensuring no dwarf leakages.
    * print_frames.c: More accurate error report (one
    place).  * print_pubnames.c: Fixing leaks and making
    some error
      message more precise (showing values).
2020-03-21  David Anderson
    * dwarfdump.c:Add flag_data_post_cleanup() in a few
      more places early termination situations.
    * print_abbrevs.c: Move some variables to the most
      local scope. Revise the while loop so we can ensure
      local alloc cleaned up in case of error. Remove
      pointless duplicate tests for zero abbrev_code.
    * print_die_stack: Refactor, adding dealloc_die_stack()
      and calling it where needed to free up local malloc
      data.
    * print_frames.c: Add more dwarf_fde_cie_list_dealloc()
      where appropriate.
2020-03-20  David Anderson
    * print_aranges.c: In case of error was not cleaning
      up allocations immediately in all cases.
2020-03-20  David Anderson
    * print_frames.c,print_dgbindex.c,print_macros.c,
      print_pubnames.c,print_ranges.c,print_reloc.c,
      sanitized.c,tag_attr.c,testesb.c, uri.c: Remove use
      of esb_append_printf() and use esb_append_printf_i
      etc instead.  Then null device will never be set up.
2020-03-19  David Anderson
    * globals.h: Using parens in the DROP_ERROR_INSTANCE
      macro to avoid accidental side effects.
    * print_die.c: Now uses more localized pointers
      where possible to make understanding the code
      simpler. Much more careful to dwarf_dealloc
      things in the face of errors in the DWARF and early
      termination of dwarfdump.
    * print_lines.c: Much more careful to dwarf_dealloc
      things in case of error.

    rangeset,DW_DLA_RANGES.
2020-03-15:   David Anderson
    * glflags.c: Now defaults to not printing the global
      alloc sums. Use --print-alloc-sums option to
      dwarfdump to print them (ensure GLOBAL_ALLOC_SUMS
      defined in libdwarf/dwarf_alloc.c).
2020-03-15:   David Anderson
    * print_pubnames.c: Reformat a too-long line.
2020-03-14:   David Anderson

      group of functions to reflect the real meaning,
      dwarf_code -> dwarf_ret_val.
    * print_aranges.c (print_aranges): Only call
    dwarf_dealloc() in
      case pa_error is non-null.
    * print_die: Initialize no_of_elements at long last.
    * print_pubnames.c: A code line was ... long. 2
    lines now.

      date string.
    * dwarfdump.c: Implements the two new options.  *
    glflags.c,glflags.h: declares and instantiates
      a new global flag gf_print_alloc_sums for the new
      option --print-alloc-sums.
    * print_die.c: Arranged correct dwarf_dealloc of
      DW_DLA_ERROR errors when calling
      dwarf_formudata/sdata and discarding errors.
2020-02-25:   David Anderson

      dwarfdump-ta-table.h dwarfdump-tt-ext-table.h
      dwarfdump-tt-table.h: updated date string.
2020-02-25:   David Anderson
    * esb.c: Slight corrections so a %-12s will ignore
    the -12
      if the string to be inserted is more than 11 bytes
      long.  Allowed use of UNUSEDARG.
    * runtests.sh: Restore the running of the testesb.c
      test program.
    * testesb.c: Added a new test case specifically for
      testing the change in esb.c. Eliminated the unneeded
      tests on allocation-size, that was not helpful,
      yet was tedious to make meaningful.
2020-02-20:   David Anderson
    * print_die.c: Removed the last snprintf the required
      fixed spaces and now use esb functions to do the
      message creation.
2020-02-19:   David Anderson
    *
    checkutil.c,common.c,naming.c,print_abbrevs.c,print_die.c,
      print_lines.c: Removed the ORIGINAL_SPRINTF versions
      in favor of esb_append_printf_[usi] versions.
      We have not been using the s[n]printf versions for
      a while now.
2020-02-16:   David Anderson
    * globals.h: Adds DWVERSION5 to use with testing for
      version number details (which matters when calling
      dwarf_srcfiles())
    * print_die.c: Now recognizes that DWARF5 is different
      from earlier versions in the way dwarf_srcfiles()
      array of string pointers is to be used.  Refactored
      the srcfiles checking to its own function to simplify
      reading the code.
2020-02-13:   David Anderson
    * dwarf_names.c dwarf_names.c,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,

2020-01-27:   David Anderson
    * print_die.c: Now attributes the correct actual form
      in more places (meaning in error messages, here and
      in the previous commit)..
2020-01-25:   David Anderson
    * print_die.c: Now attributes the correct actual form
      name (as opposed to a vaguely generic FORM name)
2020-01-16:   David Anderson
    * print_die.c: Now ensures local Dwarf_Sig8
      variables are always initialized with zero bytes.
      This does not fix bugs, but it makes the code easier
      for the reader to reason about.
    * testobjLE32PE.test.c: Removed trailing whitespace
      and fixed indentation errors.
2020-01-14:
    * dwarf_names.c,dwarf_names.h,dwarfdump-ta-ext-table.h,
      dwarfdump-ta-table.h,dwarfdump-tt-ext-table.h,dwarfdump-tt-table.h:
      Updated version string.

    * dwconf.c: Fix CoveritySan CID 206594 resource leak
      if an error reading dwarfdump.conf.
    * sanitized.c(no_questionable_chars): Fixed
    CoverityScan
      CID 206595. The code was failing to sanitize %
      characters: the test for % has been moved up a
      few lines.  do_sanity_insert() had the same problem
      with %. Fixed.  And do_sanity_insert() had a final
      line of unreachable code; now fixed by simplifying
      the code (an ASSERT added in a comment). Coverity
      Scan CID 206596.
    * print_die.c(traverse_one_die): Was failing to check
      for the normal dwarf return int and letting next
      code deal with the fallout (and leak an error
      record). Now we check and avoid any leak or surprise.
