enexpected?  are you typing things in by hand, or does your computer
have a bad RAM chip ?

try changing

    result = Py_BuildValue("i", num*num);
    PyEval_CallObject(temp, result);
    Py_DECREF(result);

to

    result = Py_BuildValue("(i)", num*num);
    PyEval_CallObject(temp, result);
    Py_DECREF(result);

or, more convenient

    result = PyObject_CallFunction(temp, "i", num*num);
    if (!result)
        return NULL;

(note that you don't really need to check for callables; the CallFunction
API will do that for you, and generate a proper exception if you pass in
the wrong thing).
