Hi,

I've uploaded a corrupt (by zzuf) H.264 video file which causes ffplay
(current revision 8403) to crash. It's available here:
ftp://upload.mplayerhq.hu/MPlayer/incoming/h264_segfault
pi-20070314T154046-ffmpeg-ffplay_crash.h264
pi-20070314T154046-ffmpeg-ffplay_crash.txt

The commandline used to cause the crash:
ffplay_g -stats pi-20070314T154046-ffmpeg-ffplay_crash.h264
Input #0, h264, from 'pi-20070314T154046-ffmpeg-ffplay_crash.h264':
  Duration: N/A, bitrate: N/A
  Stream #0.0: Video: h264, yuv420p, 320x240, 25.00 fps(r)
[h264 @ 0x847a2dc]negative number of zero coeffs at 13 5
...
[h264 @ 0x847a2dc]decode_slice_header error
[h264 @ 0x847a2dc]concealing 300 DC, 300 AC, 300 MV errors
Segmentation fault (core dumped)

FFmpeg was configured using ./configure --enable-gpl --enable-x11grab
and GCC 4.1.2 was used.

With friendly regards,
Takis
