12772	3D Accelerated Linux Guests Crash on Shutdown	h-w		"3D enabled 64-bit Ubuntu and Fedora guests crash on shutdown. In the log file (attached) the log reaches the line:

{{{
Console::powerDown(): A request to power off the VM has been issued (mMachineState=Stopping, InUninit=0)
}}}

Then a Windows exception code 0xc0000005 occurs.

The host is an Asus M5A97 EVO with a Phenom II X4 810 CPU, ATI HD 4850 GPU, 16GB RAM running 64-bit Vista Home Premium, service pack 2, and all updates.

Guests are all updated as of 4 March 2014. Guests which crash include Fedora 19 and 20, Ubuntu 12.04 and 13.10. Guest additions were built on the VMs but I don't think they have an impact on the problem.

Guests do **not** crash **every** time they are shutdown. The Fedora 20 seems to crash **almost every time**.

Virtual Box is run under a regular user with **no Administrator rights**.

The problem occurs on both pre-existing VMs which worked fine under 4.3.6 and on newly created VMs. I created a new Fedora 20 VM under a user which had not run VirtualBox before, so all user files and configuration were created by 4.3.8. The VM was created as a Fedora 20 desktop system, no LibreOffice, added packages: kernel-headers,
kernel-devel, gcc, make, dkms, vim-minimal, vim-enhanced, tcsh, xterm, git-all to enable building and installing guest additions and investigating the problem.

I've attached the user configuration file, copies of the errors reported by eventvwr, and showvminfo dumps for working and crashing configurations.
