Description: To see this issue in action, checkout trunk revision 433524. Enable build of utils/aelparse. Build with DONT_OPTIMIZE enabled will succeed, build with DONT_OPTIMIZE disabled will fail:
{noformat}
[LD] aelparse.o aelbison.o pbx_ael.o hashtab.o lock.o ael_main.o ast_expr2f.o ast_expr2.o strcompat.o pval.o extconf.o -> aelparse
hashtab.o: In function `_ast_calloc':
include/asterisk/utils.h:568: undefined reference to `ast_log_safe'
...
hashtab.o:include/asterisk/utils.h:568: more undefined references to `ast_log_safe' follow
{noformat}

This seems to be the case with or without AST_DEVMODE, it doesn't matter what other options are chosen, DONT_OPTIMIZE somehow causes the call to ast_log_safe to disappear. I'm unsure how this is possible.

Although these instructions are for testing against trunk I believe this issue applies to all branches.

I don't think this can be fixed. To detect link errors you should build Asterisk twice, once with and once without DONT_OPTIMIZE. If running the full build twice COMPILE_DOUBLE should be disabled as it would only make the build take longer.
