Looks like a gremlin in call-with-output-string, it doesn't seem to
guard against its port having been closed.
Dunno what it ought to do in that case, maybe throw an error, maybe
return #f or unspecified.

It looks like one isn't meant to close a string port before getting
the result. The manual doesn't seem to say anything about that
