[issue20918] Logging of logging exceptions can fail in 3.4 if args are unprintable

[R. David Murray]

R. David Murray added the comment:

Yes on 3.3 fixes, but you are right that it doesn't need fixed there.  This appears to be a 3.4 regression.  I used exactly the test you suggest to reproduce it on 3.4...there there is a chained traceback and Done does not get printed.  So, the original report is indeed invalid, but we've uncovered a regression.  Fortunately it is a low impact regression.

I'm guessing this arises from the improvements you made to the "fallback" logging of these errors.
