Bug description:

# Add a code block here, if required
async def test():
    async with (
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            cm(),
            # cm(),
    ):
        pass

The above code (with the final cm() commented out) will cause a Segmentation Fault on Ubuntu 22.04. This works as expected on Python3.11.

[dmgrime@dave-laptop:~]$ python3.11 breakme.py
[dmgrime@dave-laptop:~]$ python3.12 breakme.py
Segmentation fault

Note: commenting out an additional cm() works as expected in both Python3.11 and Python3.12 (no exception, no seg fault).

[dmgrime@dave-laptop:~]$ python3.11 breakme.py
[dmgrime@dave-laptop:~]$ python3.12 breakme.py
[dmgrime@dave-laptop:~]$

Note: uncommenting the final cm() works as expected in both Python3.11 and Python3.12 (exception but no seg fault).

[dmgrime@dave-laptop:~]$ python3.11 breakme.py
  File "/home/dmgrime/breakme.py", line 2
    async with (
