https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70970 --- Comment #4 from Rodrigo --- Well, without auto-vectorization the code should work (x86 allows non-SSE misaligned reads and writes). But I think understand your rationale. Thanks.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70970 --- Comment #2 from Rodrigo --- Just noticed a dumb mistake in the parameter order of memalign (_aligned_malloc is (size, alignment); memalign is (alignment, size)) but the problem persists. Also forgot that I had to use -march=native under 5.3.
