In that case always aligning the stack in threadStart would save some 
headaches to a lot of people, I think. While googling about these issues 
I found mentions of the ffmpeg case you talked about; that is because of 
them that I found the correct attribute to align the stack. some mplayer 
codecs seem to have trouble with these multithreaded alignment issues too.

If for some reason it is not desirable to patch the lib, would it be 
possible to have some easy to see disclaimer added about this problem 
somewhere?
