Xorg log with backtrace at end

Current git Xorg does run well now, but it crashes
reliably during server shutdown.

Nothing in dmesg, i915_error_state, etc.

I think that's a known one involving the double free of a GLX resource, bug 28181. The patch there has been superseded by Adam Jackson's assault on GLX...
Comment 2 Knut Petersen 2011-04-12 05:06:10 UTC 
Well, you are right again. I found

http://lists.x.org/archives/xorg-devel/2010-December/016969.html

and tried that patch. I applied it to the current git version
of the xserver code. I got a few offset warnings but patching
succeeded and the code compiled.

Result: A clean Xorg shutdown.
Comment 3 Chris Wilson 2011-04-12 05:27:54 UTC 
I'm annoyed that despite it being a proven bug fix I could never get anyone to apply it.

I do hope that in light of Adam fixing so many GLX bugs it has since been fixed in master...
