[asterisk-bugs] [JIRA] (ASTERISK-24032) warning: "_FORTIFY_SOURCE" redefined

[cloos (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=221088#comment-221088 ] 

cloos commented on ASTERISK-24032:
----------------------------------

I should add, Gentoo patches gcc adding to gcc/c-family/c-cppbuiltin.c:

+  /* Fortify Source enabled by default w/optimization.  */
+  cpp_define (pfile, "_FORTIFY_SOURCE=((defined __OPTIMIZE__ && __OPTIMIZE__ > 0) ? 2 : 0)");
+

This can be seen by running:

:; gcc -O2 -dM -E - </dev/null |grep FORT
#define _FORTIFY_SOURCE ((defined __OPTIMIZE__ && __OPTIMIZE__ > 0) ? 2 : 0)

Some other dists do this – or something like it – too.
