--- Comment #5 from Dâniel Fraga <fragabr at gmail dot com> --- (In reply to Andrew Pinski from comment #4) > You did not answer my question: "Also what instruction is the segfault > located on"? Sorry. I read too fast. Do you mean AVX instruction? I put AVX at the title because the segfault won't happen when compiling for Nehalem (or with -mno-avx). I don't know what specific instruction is causing this (what I know is that the segfault will only happen when AVX optimization is enabled). If you tell me a way to discover what instruction or how to better debug this, jusk ask and I can test here for you. Thanks you.
