I wonder which one of c++ and ms visual-something compiler is ahead in the game of creating endless problems.
Patch on the mailing list.

I have reproduced this while trying to build ffms2 master against ffmpeg master.

A patch has been submitted to the devel mailing list and approved, it will land soon in the Git tree.

I suspect this is reproducible again since f75786f3

Probably. I sent a proposed fix, with a comment to document it.
