More specifically, the environment is: Windows 8.1, Cygwin 2.3.1, GCC 4.9.3, CPU 'Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz', compilation options are '-O0 -mavx'. Is it indeed a bug in Cygwin or I don't understand something? Cheers, Ilya #include "immintrin.h" __m256 routine(void) { __m256 aux; return aux; } int main(void) { void *buf = malloc(1); __m256 res = routine(); return 0; }I believe this is due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412 , https://stackoverflow.com/questions/5983389/how-to-align-stack-at-32-byte-boundary-in-gcc has an ugly workaround which might work for you.
