New submission from STINNER Victor <vstin...@python.org>:
Sometimes, when a test fails in the main branch, unittest fails with the
following 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
I only see this error in the main branch, so I suspect that it's a recent
change.
Mark, Guido: can it be related to the recent optimization work?
