#include <xmmintrin.h>
int main()
{
float dest = 0.0;
__m128 xmm0 = {0.0,0.0,0.0,0.0};
_mm_store_ps(&dest, xmm0);
return 0;
}

[~]> gcc -msse2 -o test test.c
[~]> ./test
zsh: segmentation fault ./test
It doesn't crash when compiled with icc. Also testcase is reduced from a larger
library.

------- Comment #1 from rguenth at gcc dot gnu dot org 2008-02-02 12:33 -------
_mm_store_ps stores four(!) float values at the destination which needs to be
16-byte aligned.

I suppose you want _mm_store_ss, btw.
