Description

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:

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