New submission from Andrew Wason <[EMAIL PROTECTED]>:

ffmpeg, ffplay and mplayer crash while playing or transcoding this video. It is
MP4 (H.264/AAC) from a Sanyo HD1000 camera. It plays back OK in QuickTime player
but with some visual artifacts.

Sample video uploaded to
upload.mplayerhq.hu/MPlayer/incoming/avc-crash/avc-crash.mp4

Will post ffmpeg log in next message since roundup isn't supporting file 
uploads.

Info from gdb when ffmpeg crashes:
