Hi All,

I got two files from CVS: base_object.hpp and wrap_python.hpp.

I still get the same problem: object.c, _Py_ForgetReference, 
op->_ob_prev = NULL.

My example is simple. I built bpl_static with BOOST_DEBUG_PYTHON
defined.  I then built the following:

class Dog
{
public:
    Dog(){}
    ~Dog(){}
};

extern "C"
{
#ifdef _WIN32
__declspec(dllexport)
#endif
void initKenel()
{
    try
    {
        // create an object representing this extension module
        boost::python::module_builder kenelModule("Kenel");

        // Dog
        boost::python::class_builder<Dog> Dog_class(kenelModule, 
"Dog");
        Dog_class.def(boost::python::constructor<>());
    }
    catch(...)
    {
       boost::python::handle_exception();    // Deal with the 
exception for Python
    }

}

} // extern C

int main(int argc, char **argv)
{
    //Initialize the Python interpreter.  Required.    
    Py_Initialize();

    // initialize my module!
    initKenel();
    /* Do some application specific code */
    printf("Hello, brave new world\n\n");

    /* Execute some Python statements (in module __main__) */
    PyRun_SimpleString("import Kenel\n");
    printf("\nGoodbye, cruel world\n");

    /* Exit, cleaning up the interpreter */
    Py_Finalize();

    return 0;
}

I made sure Python20_d.lib/dll were accessible.
I build in Debug, and run it.  VC++6.0, SP4.
