Did you report this to the developers of libvpx? The crash seems deeply in their code.

I posted a bug report in the Webm project (http://code.google.com/p/webm/issues/detail?id=702)

Please reopen if it turns out that this is a bug in FFmpeg.

See TracTickets

Somehow, using valgrind, the error does not occur (does it disable x86 specific code? because it runs at 0.2 fps)
