Can confirm issue exists on multilib as well, same __strstr_sse42 crash.

I can confirm this. Can reproduce the crash in __strstr_sse42 using glibc-2.18-1-i686 and lib32-glibc-2.18-1-x86_64.

just curious and maybe stupid question but people experiencing the crash.

Do you see sse4_2 in the output of

cat /proc/cpuinfo

EDIT: The answer is yes. Just saw the attachement. Sorry for the noise.

It looks like commit f1d70dad5381352b3cad04b5ee0dd0efe2627683 is the problem.

http://sourceware.org/git/?p=glibc.git;a=commit;h=f1d70dad5381352b3cad04b5ee0dd0efe2627683

Hmm, does it work if you remove the #if/#endif added to strstr.c by that commit?

For the people having this issue, what package provides /usr/lib/libGL.so.1?

@Dalrik: was that from bisecting the issue? Have you confirmed reverting that commit fixes it?

Yes that was a bisect. Readding inline to __m128i_strloadu fixes it. libGL is owned by mesa-libgl 9.1.6-1 (lib32-mesa-libgl for the lib32 version)

EDIT: Also, a straight revert fails due to merge conflicts in locale/elem-hash.h and posix/regex_internal.h, and the build fails

Building glibc with -O3 instead of -O2 seems to help, as well.

glibc-2.18-2 in [testing]. Can people confirm the "fix"? (lib32 builds should appear soon)

glibc-2.18-2 in [testing] fix the segfault problem in running oracle jdk (more or less the same as this bug).

fixed, thanks.

lib32-glibc 2.18-2 in [multilib-testing] works as well
