VM Crash when QtGuiVBox4!QBezier::stationaryYPoints calls memcpy

[bubbafat]

Steps:

1. Create a new VM - Ubuntu Linux 64, 4GB RAM, 12 GB HD (fixed size), all other settings the default.
2. Mount the Ubuntu 12.04 x64 Live CD (ubuntu-12.04.3-desktop-amd64.iso)
3. Boot to the LiveCD
4. Install Ubuntu using the default settings
5. When you get to the reboot screen hit "reboot now"

The VM crashes. The VM is marked as "Aborted" in the UI and cannot be booted to.

This is a 100% repro on my machine. I am able to create and use other VMs without issue.

The only thing that is different from this VM to the others (besides the OS) is that this vdi file is on my F: drive which is NTFS with 64K clusters (the others are on my C: drive using 4K allocation clusters). Not sure if this detail matters.

I have a full mini dump (4GB uncompressed) available if necessary - I am hesitant to attach it to this bug report. I needed I can get a smaller one.

The call stack at the crash is:

Attaching minidump. I forgot that I could just open the full memory dump and create a minidump from it (without having to reproduce the entire error).

Please reopen if still relevant with a recent VirtualBox release.
