[issue6083] Reference counting bug in PyArg_ParseTuple and PyArg_ParseTupleAndKeywords

[Eugene Kapun]

Eugene Kapun <abacabadabacaba at gmail.com> added the comment:

Actually, this can't be fixed without modifying C API methods PyArg_ParseTuple and PyArg_ParseTupleAndKeywords, because it's possible to make an object deallocated before PyArg_ParseTuple returns, so Py_INCREF immediately after parsing would be already too late.

Here are my test cases:
test-resource.py - in Modules/resource.c, and python-bug-01.patch won't work against it.
test-ctypes.py - in Modules/_ctypes/_ctypes.c.
test-functools.py - in Modules/_functoolsmodule.c (py3k only).
