STINNER Victor  added the comment:

Is it possible that bpo-2 is a duplicate of this issue? Is it already fixed 
by GH-26768, commit ba2f32a983a08c4f64c23c187432e38908639c12?

Oops, I wanted to ping Mark Shannon, not Mark Dickinson.

[issue44288] unittest: _is_relevant_tb_level() fails because tb.tb_frame.f_globals=None

[STINNER Victor]

New submission from STINNER Victor :

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?
