BSD 4.3 Sends data after FIN?

I have a bug report from France (so it's not as clear as I'd like) that
looks like 4.3 is sending data past a FIN. There is some error condition
being exercised relating to a zero window, and the connection is terminated.
A FIN appears with data in the packet. It is acked. Later, another
packet is received with the same length (I don't know whether it is the
same data), with the updated sequence number, and still with a FIN. Thus
the data is logically after the first FIN.

Can someone check this out?
