I was going to say that the patch has no visible effect, since
PyObject_GC_Del() calls something which has the same effect as
PyObject_GC_Untrack...
But the following code crashes the interpreter! And of course the patch fixes
it...

Thanks for your help! I fear they are many other places like this one in
CPython code.

This patch seems reasonable, is consistent with the GC docs, and passed all
regression tests. Can someone apply?

New submission from Ryan Kelly r...@rfk.id.au:
According to the docs here:
http://docs.python.org/c-api/gcsupport.html
Any object that uses PyObject_GC_Track in its constructor must call
PyObject_GC_UnTrack in its deallocator. The CThunkObject in _ctypes does the
former but not the later.
