Alexander Monakov <amonakov at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |amonakov at gcc dot gnu.org --- Comment #13 from Alexander Monakov <amonakov at gcc dot gnu.org> --- Sergei Trofimovich made substantial progress on diagnosing this on Gentoo side, and according to his findings the crash is due to reading stack canary from a wrong location. This indicates that the bug is not in GCC, but in the CPU or maybe the kernel. Please see comments 73 and 74 in the Gentoo bugreport: https://bugs.gentoo.org/724314#c73
