Does the processor you are running this on support the SSE3 instruction set?
Which branch and revision of Myth is this?
Is the issue repeatable and do you have a sample?
Does this happen with ffplay on the sample?

Processor: E8400 Core2
Branch: Latest trunk
Issue is not reproducible. Happens 1 out of every 4 H.264 programs I watch, and does not happen in the same place twice.
This has been happening ever since Janne's ffmpeg merge many months ago. I have not bothered to report it, because it is not reproducible. However, I decided to go ahead and post a BT in case someone can spot a problem.

Compiling with --disable-ssse3 appears to sidesteps this segfault.

We've had another ffmpeg resync lately. Can you try this again? If it still happens, can you try reproducing it in ffplay (from ffmpeg trunk, preferably)?

Does look like this is probably fixed. Been several days and no segfaults. If I get another segfault, I will open a new ticket.
