[New-bugs-announce] [issue14934] generator objects can clear their weakrefs before being resurrected

[Antoine Pitrou]

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

In Objects/genobject.c, gen_dealloc() calls PyObject_ClearWeakRefs() before trying to finalize the generator, during which the generator object can be resurrected. This is probably a bug, since weakrefs are supposed to be cleared (and their callbacks called) only when the object is really being destroyed.
