I have reported the same bug for Clang:
https://bugs.llvm.org/show_bug.cgi?id=35902

Unlike GCC, Clang is also eager to generate unaligned "movaps" instructions,
crashing the program. Afaik GCC does not generate SSE instructions that often,
but I wonder if it can do something similar.

Clang's unaligned movaps bug: https://bugs.llvm.org/show_bug.cgi?id=35901
