Description of problem:
C# client running via SSL raises unhandled exception with message

Unhandled Exception: System.AccessViolationException: Attempted to read or write
 protected memory. This is often an indication that other memory is corrupt.
   at qpid.messaging.Connection.{dtor}(Connection* )
   at qpid.messaging.Connection.__delDtor(Connection* , UInt32 )
   at Org.Apache.Qpid.Messaging.Connection.!Connection()
   at Org.Apache.Qpid.Messaging.Connection.Dispose(Boolean )
   at Org.Apache.Qpid.Messaging.Connection.Finalize()

The issue occurs in two cases:
1. The client attempts to connect a broker, authentication fails and the exception is raised before closing the client.

2. The client attempts to connect a broker, the connection is successful, sends (or receives) messages and the exception is raised before closing the client.

Version-Release number of selected component (if applicable):

How reproducible:
100% in described cases

Steps to Reproduce:
1. Compile C++ and C# examples.

2. On the linux machine create nss database and generate SSL certificates:
# mkdir qpid_nss_db
# cd qpid_nss_db/
# echo password > ssl_pw_file.txt
# certutil -N -d . -f ssl_pw_file.txt
# certutil -S -d . -n rootCA -s "CN=rootCA" -t "CT,," -x -m 1000 -v 120 -f ssl_pw_file.txt
# certutil -S -n "<server_cert_name>" -s "CN="<hostname> -c rootCA -t ",," -m 1001 -v 120 -d . -f ssl_pw_file.txt
# certutil -S -n client -s "CN=client" -t ",," -m 1002 -v 120 -c rootCA -d . -f ssl_pw_file.txt

3. Create a directory, export certificate of authority into .cer format and client certificate into .pfx format; create a new password file:
# mkdir windir
# certutil -L -d . -n rootCA -f ssl_pw_file.txt -a > windir/qrootCA.cer
# pk12util -d qpid_nss_db -n client  -k ssl_pw_file.txt -w windir/win_pw_file.txt -o windir/client_from_nss.pfx

4. Copy the windir folder on the Windows machine and.

5. Install rootCA.cer certificate into Trusted Root Certification Authorities.

1st case:
6a]. Run a broker with configuration:
  # cat /etc/qpid/qpidd.conf
ssl-cert-name=<server_cert_name>                                                           auth=no                                                                                                             

7a] From Windows machine run csharp.example.spout example:
csharp.example.spout.exe --broker <hostname>:5671 --connection-options "{transport:ssl}" amq.topic

2nd case:
6b] Run a broker with configuration:
# cat /etc/qpid/qpidd.conf

7b] Set environment variables: 
set QPID_SSL_CERT_FILENAME=<path to .pfx certificate> 
set QPID_SSL_CERT_PASSWORD_FILE=<path to win_pw_file.txt>
8b] Run csharp.example.spout example:
csharp.example.spout.exe --broker <hostname>:5671 --connection-options "{transport:ssl}" amq.topic

Actual results:
1st case:
Connection is established, the message is delivered to the broker and the unhandled exception is raised before client's end.

2nd case:
Authentication fails and the unhandled exception is raised before client's end.

Expected results:
No unhandled exceptions should be raised in the both cases.

Comment 9 Petra Svobodová 2014-01-08 05:05:47 EST
C# and C++ clients on Windows shut down cleanly now; the issue did not occur.

Verified on packages qpid-cpp-win- on Windows 7, Windows Server 2003, Windows Server 2008 on x86 and x64; on Windows XP-x86  and Windows Server 2008 R2.
