Could you test with current git head? I see no invalid memory accesses here.

[ami_stuff]

crashes here with (not my build):

C:\>ffmpeg
ffmpeg version N-41228-g0bae666 Copyright (c) 2000-2012 the FFmpeg developers

and

(maybe can be reproduced with wine?)

[Michael Niedermayer]

cant reproduce on linux

[Michael Niedermayer]

Your gdb output is full of "optimized out" can you post one with all optimizations disabled. This could help in identifying where the issue is

[ami_stuff]

this doesn't crash anymore
