Not if the passenger meets the country's entry requirements.

It's going to cost you some extra money, but you need a new passport anyway, eventually. Put the extra money down as a learning experience to renew your passport earlier.
This is what I would suggest rather than the OP worrying about the situation. It's really quick and easy to renew a passport this way and avoids the situation of being without a passport for some time.
