Comment (by marcel123):

 Replying to [comment:2 cehoyos]:
 > Is the problem also reproducible with current git head?

 > Please provide the failing command line together with complete, uncut
 console output and for all crashes, please provide backtrace etc. as
 explained on http://ffmpeg.org/bugreports.html

 Unfortunately I don't have the current git tree and don't have the time to
 grab it and try it.  The code I was working with came from a zip file
 containing the official release.

 We are working with the libraries in a custom application, so the command
 line and console output would not be useful to you.

 I also don't have the backtrace anymore. It wasn't completely relevant
 because it wasn't crashing at the point where the heap was getting
 corrupted; it was crashing downstream on subsequent memory/heap
 operations.

 Once we debugged the problem, we fixed it in our version of the tree and
 moved forward. Since we know exactly what the cause of the problem was we
 thought we would report it here. We are no longer blocked by this issue,
 so you may close the bug regport if you feel it is not useful.
