In my code I have the dtors of my connection objects emit a message when they are called. Since they use the shared_from_this trick they are invoked when the overlapped structure is been deleted since they are bound to them.
So I am pretty sure I can see when the call to destruct the overlapped is missing.
On the other hand I can see that the socket is closed properly since the client receives the shutdown request.
I would be glad if you could give me another hint which kind of debug message would be helpful to you.
Don't worry, what you describe above already sounds like sufficient evidence.
On the other hand, perhaps some (mathematical) reasoning also can help: If the socket is closed, which property guarantees that the queued completion status invoked with zero timeout will see the associated overlapped for sure? Or put it another way: why not waiting infinitely when we are sure there must be something pending? Why zero timeout?
That's exactly what I meant by "maintaining a counter of outstanding operations", and I've just checked in such a change. Please let me know how it goes. Cheers, Chris
