Can't reproduce this in Gnome Shell

Can you gdb to get a better backtrace or run
"addr2line -i -e /usr/lib/xorg/modules/drivers/intel_drv.so  0x7c6b7 0xe0940 0x4e448 0x50b6e"

I think this will mask the bug:

commit ded05e8abb248664124d2b86f77c27497a252c4e
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Jun 23 22:15:56 2014 +0100

    sna: Allow scratch pixmap to allocate linear GPU bo
    
    When allocating a scratch pixmap, we do so in the expectation that
    rendering on the GPU is always preferrable, so even allocate a small
    linear bo.

But I do need to know where it fell over in case it is not obvious.

Sorry, hope it's more useful now.
addr2line says

Yes. That should be fixed by ded05e8abb248664124d2b86f77c27497a252c4e. Thanks a lot!
