I have not been able to separate the problem out into a test case. But,
I can send you my source code if you like. There is less than 1000
lines OpenGL related code. I would just like to know if it crashes your
machine. Also is there any kind of post crash dump from the kernel that
i can see?

I think it is a concurrency issue. I have a separate GL rendering
thread. I do a XSync before i sync with the rendering thread to
reshape the viewport. I have prevented this problem by adding some
delay before the reshape handler returns.
Any ideas?
it's hard to say without seeing the code. If you make a test case
showing the problem we will look into it..
