[Libva] Crash/Exception/MemoryCorruption when decoding with libva

[Timo Rothenpieler]

Ivy Bridge, i3-3220, HD2500.
I'v rebooted the machine several times and tried a couple diffrent 
live-distributions and software-versions. It affects every h264 video i 
tried, but only h264.

There's nothing more clear, sometimes it crashes in a totaly unrelated 
part of the programs, sometimes in BeginPicture, sometimes in EndPicture 
or some other libva function.

I have already ordered a replacement-CPU cause a hardware defect is the 
only idea left.
