[issue42762] infinite loop resulted by "yield"

[Steve Stagg]

Steve Stagg <stestagg at gmail.com> added the comment:

That /is/ weird.  I tried a few variations, and it looks like something is being stored on the exception that is stopping the loop behaviour.

"except BaseException:"      <- infinite loop
"except BaseException as e:" <- NO loop
"except BaseException as e:
   del e
   yield from foo()"         <- infinite loop

So is this a reference being retained somewhere?
