Originally I posted ticket #495 about a crash here:

https://ffmpeg.org/trac/ffmpeg/ticket/495

This ticket was closed but I never saw any difference in the status of the crash on my machine. It has come to my attention that while the crash seemed the same to me, this is most likely a different case. That is, it may not happen with 64bit etc.

Using this file (hidef_crash_cut.wmv 20mb) it crashes everytime for me on windows x86 32bit.

​http://www.datafilehost.com/download-3cd0d3f7.html

Looking at the details below, it appears to be the same case as in ff_mspel_motion as originally posted here.
