Hi,
I apparently missed your request for the output of such a session
somehow. Attached is a typescript.
You won't see it totally missing out on the function call return, since
I couldn't reproduce that at this point (and I couldn't remember a case
where it happened). I have no reason to believe, however, that this
behaviour has gone away.
This is an optimized binary; but it happens with software compiled with
-O0, too.
If you need me to do anything else, just let me know.
