---------------------------------

             Summary: C++ HelloWorld messaging client crash closing AMQP 1.0 connection on
Windows
                 Key: QPID-5363
                 URL: https://issues.apache.org/jira/browse/QPID-5363
             Project: Qpid
          Issue Type: Bug
          Components: C++ Client
    Affects Versions: 0.25
         Environment: Windows, native C++ client, Amqp 1.0 protocol, Visual Studio 2008, 32-bit,
Debug
            Reporter: Chuck Rolke


HelloWorld connects, send all messages, and then crashes with an access violation during connection::close().
Gordon and I tracked the issue down to a double free of TcpTransport aio objects, with the
__vftable containing all 0xdddddddd pointers indicating that the object was already deleted.

Without the proposed fix, a locked 'closed' flag, the code crashes about 10% of the time.
With the fix it proceeds indefinitely.
