[issue38006] Crash in remove() weak reference callback of weakref.WeakValueDictionary at Python exit

[Pablo Galindo Salgado]

Pablo Galindo Salgado <pablog...@gmail.com> added the comment:

Wait, I just checked and the call is done manually:

static void
ctypedescr_dealloc(CTypeDescrObject *ct)
{
    PyObject_GC_UnTrack(ct);
    if (ct->ct_weakreflist != NULL)
        PyObject_ClearWeakRefs((PyObject *) ct);

I am not sure call to PyObject_ClearWeakRefs from tp_dealloc is safe.
