The patch causes crashes. If I define
def cell(o):
def f(): o
return f.__closure__[0]
def f():
a = 1
b = 2
def g():
return a + b
return g
g = f()
then I find
g.__closure__ = None; g() -> crash
g.__closure__ = (cell(3),); g() -> crash
g.__closure__ = (1, 2); g() -> SystemError *
g.__closure__ = (cell(3), cell(4), cell(5)); g() -> returns 7
* SystemError: ..\Objects\cellobject.c:24: bad argument to internal function
