New submission from Ronald Oussoren <[email protected]>:
The following crashes the interpreter in Python 3.11, and works fine in older
versions:
# --- script.py
import types
class MyModule (types.ModuleType):
__slots__ = (
"_MyModule__a",
"_MyModule__b",
)
def __init__(self, name):
super().__init__(name)
m = MyModule("name")
# -- end of file
The key in this is the ``__slots__`` definition: The script does not crash
without ``__slots__``, or with a slots tuple with 1 item.
This is a reproducer based on code in PyObjC.
