Note the first warning is definitely not a GCC bug and should be fixed in the sources: 1.15.0/xkb/xkbInit.c:690:22: warning: type of 'XkbDfltAccessXOptions' does not match original declaration [enabled by default] extern unsigned char XkbDfltAccessXOptions; ^ /var/tmp/portage/x11-base/xorg-server-1.15.0/work/xorg-server-1.15.0/xkb/xkbAccessX.c:58:16: note: previously declared here unsigned short XkbDfltAccessXOptions = ^ ----- CUT ---- You are going to have to try to reduce the testcase. Also just this one file is not enough to reproduce the issue as this happens only with -flto it seems.
