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

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().
