https://docs.python.org/3/c-api/structures.html#c.PyObject_HEAD says that the macro should be used for creating new types and that it has ob_type. Unfortunately at some point (@61466 perhaps) that definition in object.h was changed. This affects other pages too (at least https://docs.python.org/3/extending/newtypes.html). I encountered this while checking if a C extension (imposm.parser) could be trivially ported for Python 3. Unfortunately not. I suppose self->ob_type should be replaced with Py_TYPE(self) but that isn't really clear from the docs.
