You shouldn't call PyObject_FREE yourself, but instead rely on

So, instead of commenting out Py_DECREF and keeping PyObject_FREE, I'd
recommend doing the reverse. That way, if a reference is still living
in the frame, the object doesn't get deallocated too early.
Humm. Now the behaviour is as follows:
with assignment to local variable
----------------------------------
* start_response = PyObject_NEW(...) -> start_response->ob_refcnt=1
* wsgiapp(environ, start_response) -> ob_refcnt=2
* Py_DECREF(start_response) -> ob_refcnt=1
without assignment
------------------
* start_response = PyObject_NEW(...) -> start_respinse->ob_refcnt=1
* wsgiapp(environ, start_response) -> ob_refcnt=1
* Py_DECREF(start_response): CRASH
I think I'll compile Python with debug support to check out what's going
wrong in the second case.
