--- Comment #2 from Ivan Bodrov <securesneakers at gmail dot com> --- 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
