--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I cannot reproduce the valgrind errors with any version of GCC, using valgrind
3.14.0

My guess is that these are false positives from valgrind, because it doesn't
know about the SSE4 tricks in your glibc. In other words, this is not a GCC bug
(and probably not a bug at all).

I'm not sure what comment 1 is saying, could you please provide a testcase?
