Hi.
Is it possible to provide a repro?
It would be good to verify what is causing the problem.
[IOW, how is f_smob->inferior becoming NULL?]

On a related note,
It's debatable whether this predicate should throw an exception if either the
inferior goes away or if the inferior exits.
Returning #f would still be reasonable in those circumstances.
The code is the way it is currently because that's how the python version
works.
[That's not the problem here. Just thinking out loud about a related issue.]
