VirtualBox SegFaults / crash when resumed from standby

[Jerome Poulin]

If I suspend my virtual machine, then resume it, VirtualBox crashes and the machine appears as aborted. It could be a problem on my side, but anyway, here's a backtrace: Backtrace: ​http://ticpu.net:8080/~jerome/vbox-xp-resume-crash.7z
