$ gcc-4.3.orig-HEAD -c pr.c -o /dev/null pr.c: In function 'f1': pr.c:3: warning: '__weakref__' attribute ignored pr.c: In function 'f2': pr.c:7: warning: '__weakref__' attribute ignored while with combine and the original testcase, current trunk still gives: $ gcc-4.3.orig-HEAD -c f1.i f2.i -combine -o /dev/null /tmp/ccmg6Twk.s: Assembler messages: /tmp/ccmg6Twk.s:3: Error: symbol `__gthrw_pthread_once' is already defined -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31537
