--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- Hmm, I can't reproduce with my FSF 5.1 or 5.2 builds (release checking) but I can reproduce with my current GCC 5 branch development build (checking enabled): > /abuild/rguenther/gcc5-g/gcc/cc1 -quiet -O2 -m32 -g atof01.i > -fstack-protector -funwind-tables -fasynchronous-unwind-tables Segmentation fault the above is on x86_64 with -m32 (original report was for native i?86).
