STINNER Victor <vstinner at python.org> added the comment:
Maybe the problem is related to Python frames. I think Mark Shannon made changes related to frames recently in 3.10 and main branches.
It's strange that I got such error:
File "C:\vstinner\python\main\lib\unittest\result.py", line 205, in _is_relevant_tb_level
return '__unittest' in tb.tb_frame.f_globals
TypeError: argument of type 'NoneType' is not iterable
It's also strange that two crashes occurred while reading a traceback:
Windows fatal exception: access violation

Extract of test_ssl.py:
def handle_error(prefix):
exc_format = ' '.join(traceback.format_exception(*sys.exc_info()))
...
Maybe sometimes somehow, frames are invalid.
Maybe test_ssl/test_httplib only makes the crash more likely, but there is a regression to frames somewhere.
