# The debug configuration adds the "address sanitizer" to check for out of bounds behavior and such.
# You may wish to set the following environment variables during runtime as well:
#
# export ASAN_OPTIONS=debug=true:strict_string_checks=1:detect_stack_use_after_return=true:detect_invalid_pointer_pairs=99999:
#   detect_container_overflow=true:detect_odr_violation=2:check_initialization_order=true
#
# Compiler directives (for internal use only):
#
# NO_POSIX_THREADS      - No multi-threaded unit testing - only effective for unit test.
# NO_FAST_ENCODE        - Drop fast encoding support - only for internal use.
