3.11.0a0).
==================================
import weakref
class Object:
def __init__(self, arg):
self.arg = arg
def test_set_callback_attribute():
x = Object(1)
callback = lambda ref: None
callback = weakref.ref(callback, x)
with test_set_callback_attribute():
pass
test_set_callback_attribute()
==================================
Crashes on the master (Python 3.11.0a0)
