[FFmpeg-user] Sinus error

I've included libav* libraries into our software package. When capturing 
and encoding animations some interpolation calculations (including sin() 
calls) are done in our software.
The error occurs in our source code but is somehow related to libav. If I 
do the same calculations without capturing and encoding everything works 
as expected.
If I use the libav libraries that we used before (built nearly 1 year ago) 
the error does not occur.

where does this fail? are you using ffmpeg executable or libav*?
