the shader parameters are created internally by OpenSG as it provides
some uniform variables that are available to shaders.
I don't think there are any Images created though, so those are probably
part of your model.

the above may free the memory, but if the objects you destroy are still
referenced somewhere you also introduce dangling pointers, which I
suspect cause the crashes later on. I think your best bet is trying to
find which objects that are alive where part of your scene, then see why
they still have references.

On windows the OpenSG debug libraries have names that end with a D to
distinguish them from the release libs. I'm sorry this and the fact that
mixing debug and release libs on windows causes strange runtime errors
is about all I know about development on windows, so I can't really help
with that.
Hope it helps,
Carsten
