GStreamer application access violation in random locations

[pfarmer]

Hi,

i am trying to run GStreamer within a Simulink C++ S-function. It works
occasionally, but unfortunately it does crash every now and then at
GStreamer functions. I guess its a multi-threading problem. But as far as I
could see, all of the gstreamer functions all called from within the same
thread (from within S-Function callback functions). I also tried to protect
each call with a mutex ... no sucess.

I ran out of Ideas on how to tackle this. Also If its a bug, how could I get
the necessary information?
What could i try to find the problem?
