My program crashes while executing a TCPRelease with a correct stream
(does what is expected of it until the TCPRelease).  The crash is actually
a MacsBug break in MacTCP and the message "MacTCP -- Duplicate IOC" appears.

This crash happens just after a kAEQuitApplication event has been received
from the Finder, in the routine taking care of closing the current stream
connection (with TCPAbort) and releasing the stream (with TCPRelease).

I can't find any information about that MacsBug message in the MacTCP 
Programmer's Guide so I am turning toward the knowledge of the Net for help.
What causes this break (the answer: "a duplicate IOC" will not be enough :-)?

Jerome
