Subject: 2nd bug fix for regexp(3), in regsub()
Newsgroups: mod.sources
Approved: jpn@panda.UUCP
Mod.sources: Volume 4, Issue 33
Submitted by: genrad!decvax!utzoo!henry
I cringe with embarrassment! Another bug in regexp! In regsub.c, the
following line (line 72 in the original distribution):
if (*(dst-1) == '\0') { /* strncpy hit NUL. */
should read
if (len != 0 && *(dst-1) == '\0') { /* strncpy hit NUL. */
This shows up as an occasional spurious complaint from regsub about
"damaged match string"... *if* the program invoking it, and the compiler
compiling it, happen to interact just right. It didn't show in any of
my tests because mine don't.
My thanks to H}vard Eidnes for finding this.
