New submission from Antoine Pitrou <pitrou at free.fr>:

PyWeakref_GetObject() returns a borrowed reference, which can therefore become invalid at any time (especially when the GIL gets released). This provides a way to crash the interpreter deliberately.
The returned reference should be incref'ed immediately before any other action is taken.
