Description Kaj-Michael Lang 2008-03-05 03:28:52 UTC 
All but one liboil test segfault (and all apps using liboil) segfaults under Xen. 
Version 0.3.12 is ok, everything runs fine.

Xen is version 3.2.0 and kernel is 2.6.21 from http://hg.et.redhat.com/kernel-dev/linux-2.6.21-xen-3.1.0

Disabling mmxext in liboil/liboilcpu-x86.c makes it work.

This seems unlikely to be a liboil bug, but rather with Xen.
Comment 2 David Schleef 2008-05-12 17:41:43 UTC 
Any chance you could do a git-bisect between 0.3.12 and 0.3.13 to see which commit affected it?
