Doesn't crash for me on x86_64-linux. The testcase is buggy, because the x and
y heap arrays are uninitialized, could contain any values including signalling
NaNs etc.  Nothing is vectorized here (you are just compiling with -O2, not -O3
-ffast-math that would be needed for vectorization in this case).  I see
nothing wrong on the GCC side here, so either your OS doesn't support AVX, or
the assembler is buggy, ...
