Indeed, 5c5 < void dct64_sse(float *a,float *b,float *c) --- > void __attribute__ ((force_align_arg_pointer)) dct64_sse(float *a,float > *b,float *c) fixes on 4.2. BTW, this issue has particular importance for mingw32 multithreaded programs, since Win32 API CreateThread or the corresponding CRT _beginthreadex functions do not guarantee that the stack will be 16-byte-aligned on entry to the thread start-function callback. Marking the thread start function with force_align_arg_pointer attribute fixes. Hmm should that go in gcc.info? Danny -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28069
