Subject [jira] [Created] (PROTON-1615) c++: container leaks if exception thrown by handler.
Date Fri, 06 Oct 2017 20:20:00 GMT
Alan Conway created PROTON-1615:

             Summary: c++: container leaks if exception thrown by handler.
                 Key: PROTON-1615
                 URL: https://issues.apache.org/jira/browse/PROTON-1615
             Project: Qpid Proton
          Issue Type: Bug
            Reporter: Alan Conway
             Fix For: proton-c-0.19.0

An exception throw by a handler is re-thrown out of container.run() as expected, however
the container does not shut down cleanly and many leaks are reported by valgrind or asan.
The container should be exception-safe.

To demonstrate the problem apply this small patch to the helloworld_direct example.
