Thanks for your effort. I checked out revision 284 and compiled it,
but the problem is still the same. As I didn't have any crashes with  
1.1.1,
I don't notice any change of behaviour with the new code.

I should mention that I usually don't load midi files, but work with
noteon / noteoff from the API, and tried playing midi files just for
debugging. So it's unlikely that my problem lies in fluid_midi.
