I have seen this if you try to mix object code compiled for debugging (_DEBUG macro is defined) with non-debug objects (_DEBUG is not defined).

There is a line in the python core code that #defines Py_InitModule4 to another name (Py_InitModule4TraceRefs) to trigger a "link-time error" (!sic) if you mix objects.

Make sure you link against a python debug library when you compile for debugging and vice-versa.
