Making the object kill itself after start() solves the problem.

failCallback(socket, -1, std::string(e.what()));
socket.close();
}
// Seppuku!
delete this;

> Memory leak when calling qpid::messaging::Connection::open()
> ------------------------------------------------------------
>
> Key: QPID-7187
> URL: https://issues.apache.org/jira/browse/QPID-7187
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: qpid-cpp-0.34, qpid-cpp-1.35.0
> Environment: Windows 7, using ActiveMQ 5.13 as broker
> Reporter: Jeff Yeoh
> Labels: c++, memory-leak, qpid::sys::windows::AsynchConnector,
> windows
>
> Memory leak detected using _CrtDumpMemoryLeaks();
> It happened whenever qpid::messaging::Connection::open() is called. Even
> though by the end of the session, I called connection.close() to close the
> connection, the leak still happens.
> Here's the snapshot of the code:
> qpid::messaging::Connection connection(brokerUrl, protocolConnectionString);
> // Now send the message
> try
> {
> connection.open();
> qpid::messaging::Session session = connection.createSession();
> qpid::messaging::Sender sender = session.createSender("channel");
> sender.send(message);
> session.sync();
> connection.close();
>
> }
> catch (const std::exception& error)
> {
> connection.close();
> return false;
> }
> Here's the summary of memory leak:
> Detected memory leaks!
> Dumping objects ->
> {26638} normal block at 0x00A6F1E8, 8 bytes long.

> Note that I did not use the C++ broker. I used ActiveMQ 5.12 as the broker
> using AMQP 1.0
