New submission from Alan Robertson :
When an exception "as" variable occurs, it deletes local variables with the
same name. This is certainly surprising, and doesn't appear to be a documented
behavior (but maybe I don't know where to look). The word "bug" comes to mind.
Alan Robertson added the comment:
Thanks for your kind explanation. I may even vaguely remember seeing this
sometime in the past. Thanks much for your time!

There are a variety of different reasons this can fail, not just on MacOS. You
could give it a bad IP address of a server, etc. [That was my particular case].

As far as I know, this only happens during shutdown. During shutdown it has
already removed the attribute as part of the teardown process. In this case
adding the attribute at the begining will do no good.
