I am getting a VM crash when changing the display mode few times (through setDisplayMode()) on Cinnabar with Nvidia GeForce4 MX440 when OGL is turned on.

This is noticed since mustang-b56 and this machine is installed with Cinnbar-b40 (GA). Not reproducible on Win32, default mode on cinnabar.

I have attached the test and the output of 'xdpyinfo'. Run the test. Try changing the display mode 5-6 times by choosing from the list of display modes shown. You would see a VM crash.

Here is the crash info:
