STINNER Victor <vstin...@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
Current thread 0x000009e0 (most recent call first):
File "D:\a\1\s\lib\linecache.py", line 63 in checkcache
File "D:\a\1\s\lib\traceback.py", line 375 in extract
File "D:\a\1\s\lib\traceback.py", line 494 in __init__
File "D:\a\1\s\lib\traceback.py", line 132 in format_exception
File "D:\a\1\s\lib\test\test_ssl.py", line 262 in handle_error
and:

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.
