Any ETA? I would appreciate to see my contribution being merged.

Batuhan, the current code is not doing what it's supposed to do in bogus_code_obj.py (i.e. no crash after 3.8 and above in master and branches). This still make the issue valid I guess.

```
$ ./python -V
Python 3.8.6+
$ ./python -V
Python 3.10.0a2+
$ ./python Lib/test/crashers/bogus_code_obj.py 
Traceback (most recent call last):
  File "/usr/home/sbz/github/cpython/Lib/test/crashers/bogus_code_obj.py", line 17, in <module>
    co = types.CodeType(0, 0, 0, 0, 0, b'\x04\x71\x00\x00',
TypeError: code expected at least 14 arguments, got 13
```

I would be happy to update and fix it instead if you think it's better that way. Please let me know, it will be great to see my first submission being treated.
