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

             Summary: assertion in transport_consume when authentication fails: Assertion `n == (-1)' failed
                 Key: PROTON-732
                 URL: https://issues.apache.org/jira/browse/PROTON-732
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: 0.8
            Reporter: Gordon Sim


Running the messenger recv example against the java broker (both from latest trunk at time of raising this issue), if the broker expects authentication and you don't specify a username and password then the resulting sequence causes an assertion in the proton-c library.
