Thanks to your answer, @ned.deily.

Sorry to insist, but are you sure this is a duplicate of issue18075 / 
issue35542?

According to the discussion in issue36272, it seems this is not related to 
stack exhaustion nor to issue18075.

Also, @remi.lapeyre suggested that a fix could be possible by modifying 
ceval.c. (re-raise RecursionError if it has been cleared).

issue18075 and issue35542 are both of status "closed", I would expect this 
issue to be duplicate to an "open" issue because there is a clear reproducible 
"bug" which crashes the interpreter.

There is also the problems still remaining in logging Handlers that I linked.

I think this is an issue with how recursion error are handled in ceval.c, this 
is related to "tstate->overflowed" and "tstate->recursion_depth > 
recursion_limit + 50".
If I understand correctly, this is implemented like this to allow gracefully 
catch and handle RecursionError from the calling function.
For example, why not re-raise the exception if the first one could not be 
handled correctly?
