[Quickfix-developers] [CVS] ThreadedSocketAcceptor crashes on version mismatch

[Caleb E. <cal...@gm...>]

Using CVS code as-of 2005-02-25.  If a client connects to a QF
acceptor which is using the ThreadedSocketAcceptor and there is a
mismatch between the FIX BeginStrings for that session, the acceptor
application crashes.  Using the single-threaded SocketAcceptor, no
crash happens; the acceptor closes the connection gracefully (though
nothing is logged).

Thread 1 is the thread that crashed the app:
