--- Comment #13 from Martin Sebor <msebor at gcc dot gnu.org> --- (In reply to Franz Sirl from comment #7) > And on x86_64 a profiledbootstrap with --enable-checking=yes fails like this: I have just confirmed this by doing the same. My profiledbootstrap shows the following warnings: Diagnostic Count Unique Files -Wformat-length= 3 2 1 -Wimplicit-fallthrough= 58 11 4 -Wmaybe-uninitialized 10 6 5 -Wnonnull 17 6 4 With the following unique -Wnonnull instances: cc1plus: warning: argument 1 null where non-null expected [-Wnonnull] /opt/notnfs/msebor/src/gcc/trunk/gcc/gengtype.c:1760 /opt/notnfs/msebor/src/gcc/trunk/gcc/gengtype.c:1762 /opt/notnfs/msebor/src/gcc/trunk/gcc/gengtype-parse.c:951 /opt/notnfs/msebor/src/gcc/trunk/gcc/gengtype-parse.c:952 /opt/notnfs/msebor/src/gcc/trunk/gcc/vec.h:1613 The -Wnonnull warnings all look justified to me (as best I can tell), but also easily avoidable.
