 Any attemot to transcode the movie file ffmpeg-crash-around-frame-60.wmv,
 which was uploaded to http://upload.ffmpeg.org/upload/, causes ffmpeg to
 crash around frame 60.
 This happens on a 64bit windows7 machine running ffmpeg downloaded from
 http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-
 git-d049257-win32-static.7z as well as earlier versions of ffmpeg (like
 ffmpeg version N-31932-g41bf67d, built on Aug 16 2011 18:54:12 with gcc
 4.6.1).
 Any of the following commands replicates the crash:

 ffmpeg.exe -i ffmpeg-crash-around-frame-60.wmv -y video.wmv
 ffmpeg.exe -i ffmpeg-crash-around-frame-60.wmv -y video.mp4
 ffmpeg.exe -i ffmpeg-crash-around-frame-60.wmv -vcodec libx264  -s 960x540
 -r 25 -ar 22050 -b 1993846 -y video.flv

 You can also download the original, full sized, video (around 50MB) from
 our servers at:
 http://media.webcollage.net/rwvfp/wc/cp/3493374/module/instantupdatetest/_cp/products/1318977439061
 /tab-da6bd996-030a-4d8d-b4a7-105c57117116/resource-3c1aaa56-90fd-
 4fb5-9383-e0606761a4ca.wmv

 Note: ffplay does play the movie to its end.

 Running ffmpeg -v 9 -loglevel 99 -i on the movie produces the following
 output:
