What version of the product are you using? On what operating system?
- home made windows executables 0.7rc7/0.7rc6 both 32bit and 64bit. built
using mingw64 (i686 and x86_64) on Ubuntu 12.04.
- downloaded windows 07rc7 executables(32/64) from this site.
- ffmbc0.7rc built on OpenSuse 12.1 and also Ubuntu 12.04 64bit

Please provide any additional information below:
- With the same source file current ffmpeg git master fails to encode, but
doesn't segfault.
- ffmpeg git branch release/0.11.1 is able to de-/encode.

- Full commandline run (with -v 3) and everything the program printed
without the repeating parts.

- Upload your sample somewhere and supply url
I can't post this .wmv to public.
But I can provide you with a download link via email if you want.
The .wmv file itself is user generated content uploaded to our website.
Don't blame me for it's silly content or how it's made. ;-)
