Andi Vajda commented on PYLUCENE-66:
------------------------------------

The installType function in jcc/jcc3/sources/functions.cpp is supposed to be
```
void installType(PyTypeObject **type, PyType_Def *def,
                 PyObject *module, char *name, int isExtension)
{
    if (*type == NULL)
    {
        *type = makeType(def);

        if (isExtension)
        {
#if PY_VERSION_HEX >= 0x030b0000
            Py_SET_TYPE(*type, PY_TYPE(FinalizerClass));
#else
            Py_TYPE(*type) = PY_TYPE(FinalizerClass);
#endif
            Py_INCREF(PY_TYPE(FinalizerClass));
        }

        PyObject *module_name = PyModule_GetNameObject(module);

        if (module_name != NULL)
        {
            PyDict_SetItemString((*type)->tp_dict, "__module__", module_name);
            Py_DECREF(module_name);
        }

        PyModule_AddObject(module, name, (PyObject *) *type);
    }
}
```
