For Python/traceback.c I have created a separate bpo-31949. This code looks wrong and needs other changes.

The feature seems to be implemented so the PR probably should be closed.

try:
    raise Exception('first exception')
except:
    raise Exception('second exception')

Traceback (most recent call last):
  File "main.py", line 2, in <module>
    raise Exception('first exception')
Exception: first exception

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "main.py", line 4, in <module>
    raise Exception('second exception')
Exception: second exception

The PR title is misleading. The PR is to keep the previously overridden exception in a bunch of C functions: _ctypes_extend_error(), call_exc_trace(), call_trace_protected().

This PR is attached to gh-73180, which is already completed: the fix for that issue landed through other changes, and this PR's approach was not taken or has since become obsolete. Closing to cull the number of open pull requests. Do not reopen this pull request without getting a go-ahead from a triager or core developer.
