Can't, it's fully embedded inside the application and fully loads
C-classes from C-land memory without any files or libraries.

Shutting down. It happens though also if I trigger an error for example
using
if( ! PyArg_ParseTuple( args, "iiii", &x1, &y1, &x2, &y2 ) ){
return NULL;
}
and proving for example floats instead of integer.
So it happens as soon as the GC is involved. Could it be a tp_* function
that is marked optional is actually not optional at all? According to
the documentation I need only this:
@@@@@@
typeObject = new sObjectType;
memset( typeObject, 0, sizeof( sObjectType ) );
typeObject->tp_name = "Dragengine.Gui.Graphics.Graphics";
typeObject->tp_basicsize = sizeof( sObjectData );
typeObject->tp_flags = Py_TPFLAGS_DEFAULT;
typeObject->tp_doc = "Graphics Object";
typeObject->tp_methods = vMethodsInstance;
typeObject->tp_new = ( newfunc )spModuleGraphics::cfNew;
typeObject->tp_init = ( initproc )spModuleGraphics::cfInit;
typeObject->tp_dealloc = ( destructor )spModuleGraphics::cfDealoc;
typeObject->ownerClass = this;
PyType_Ready( typeObject );
Py_INCREF( typeObject );
PyModule_AddObject( pPyModule, "Graphics", ( PyObject* )typeObject );
@@@@@@
where sObject is:
@@@@@@
struct sObjectType : public PyTypeObject{
spModuleGraphics *ownerClass;
};
@@@@@@
but maybe the documentation is missing something there?

Not in GenToo yet as far as I know.
