Aha, so Gentoo's libm has SSE stuff included because of my
compilation settings for the OS. That explains the issue.
Thanks for your help everyone.

That's what the REPE (0xf3) prefix means, yes, but in this case
it isn't really a REPE prefix at all. The sequence was 0xf3 0x0f which
is an SSE instruction that valgrind 1.9.6 certainly won't handle.
