----------------------------------------

             Summary: Enabling DONT_OPTIMIZE can cause link errors to be lost.
                 Key: ASTERISK-24923
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24923
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/BuildSystem
    Affects Versions: 13.2.0, 11.16.0, SVN
            Reporter: Corey Farrell


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.
