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; } -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
