Comment 2 for bug 1510941

This looks like bug 91577 (hard to tell with the incorrect stack traces). That was from mishandling an allocation failure.

Could you compile xf86-video-intel from http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/ with ./configure --enable-debug so that I know exactly what version you have plus include a little more debugging information?
