Attachment: AsynchIO.cpp.diff
David, could you please try the attached AsynchIO.cpp.diff with your test case?
It goes back to your original diagnosis that the issue is in AsynchIO.cpp - my
other fix took care of the broker cases, but left a leak with the client where
the operations are done in reverse order, usually.

> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: 0.5

> I'm experiencing a memory leak when using the client library on Windows (0.5
> release) when sending a single request. From what debugging I've done so far
> it looks like the The AsynchIO object used by the TCPConnector is not being
> deleted. When the connection is being closed aio->queueForDeletion() is
> called from TCPConnector::closeInternal().. However in
> AsynchIO::queueForDeletion() aio.opsInProgress > 0 so the 'delete this'
> branch is not done. There are no more queueForDeletion() calls made on the
> aio object (after opsInProgress is 0) and so it never gets deleted. The
> ConnectionImpl object involved is not cleaned up either, the shared_ptr to it
> has a non-zero ref count but I'm guessing it's related to the AsynchIO object
> not being cleaned up.
> There used to be some code in AsynchIO::completion() that seems like it would
> do the necessary delete (see below). It was removed with code changes in
> https://issues.apache.org/jira/browse/QPID-1550 because 'It fixed a memory
> corruption on the broker side by deleting too early' (from Steve H.)
> - // Lock released; ok to delete if all is done.
> - if (opsInProgress == 0 && queuedDelete)
> - delete this;
