[Quickfix-developers] Session disconnect/send synchronization patch

[Gene G. <mus...@ya...>]

I have FIX:Session that has messages send to it from
multiple threads. I have discovered (the hard way)
that under certain conditions Session::send crashes.
It happens when simultaneously there is a
Session::disconnect called from another thread, for
example when FIX session counterpart closes socket. 
Session::disconnect deletes m_Responder, if that
happens after Session::send checks for m_Responder for
presence, but before it is finished using it, crash
ensues.
The fix is to guard Session::disconnect with the same
mutex that guards Session::sendRaw.
I have attached patch that does just that.

Gene
