i just started getting into the whole embedded languages thing and python looks so promising. however i was messing around looking at code snippets and generally playing around with the boost.python / python API when i got this strange debug runtime assertion error from Py_Finalize(), this is the assert that failed that happened in Py_Finalize()

/*
* If this ASSERT fails, a bad pointer has been passed in. It may be
* totally bogus, or it may have been allocated from another heap.
* The pointer MUST come from the 'local' heap.*/
ASSERTE(_CrtIsValidHeapPointer(pUserData));


This is source code i used, note: everything compiled and linked fine.
   
#include <stdio.h>
#include <string>
#include <boost\python.hpp>

struct World{
	void Set(std::string m){ msg = m;}
	std::string Greet(){return msg;}
	std::string msg;
};

BOOST_PYTHON_MODULE(hello){
	class_<World>("World")
		.def("Set", &World::Set)
		.def("Greet",&World::Greet)
	;
}


int main(){

	Py_Initialize();
	inithello();
	if(PyRun_SimpleString( "import hello\n"
			       "planet = hello.World()\n"
			       "planet.Set('Kick Ass!')\n"
			       "print planet.Greet()") == -1){

		printf("Error Running script");
	}

	Py_Finalize();

	return 0;
}

the error only occurs in the debug build. im using Python2.2 and boost 1.30.2 . I would like to know why this assert failure is happening. i cant see any reason why it would happen except for maybe the custom module being loaded.
