New submission from Xinmeng Xia <xi...@smail.nju.edu.cn>:
The following crashing can only reproduce on Python3.11. In this case, we
import "asyncio" after deleting a coroutine object and before cleaning it up,
leading to crashing.
test.py
=======================
async def f():
pass
f = f()
frame = f.cr_frame
del f
import asyncio
frame.clear()
======================
>>>Python3.11 -Werror test.py
Exception ignored in: <coroutine object f at 0x7f860ad9cdd0>
