--- Comment #3 from Jon Levell <gcc-bugspam at coralbark dot net> --- I'm surprised this was closed invalid. "While the x86 architecture originally did not require aligned memory access, and still works without it, some SSE2 instructions on x86 CPUs do require the data to be 128-bit (16-byte) aligned" I'm not doing anything SSE2 related. I'm surprised this is considered undefined behaviour?
