Description

Grab the latest code from dispatch/proton and compile

Use the following config file to start the router (note that the host specified in the connector - some-host - is invalid)

router {
    mode: interior
    id: Router.B
}

connector {
   host: some-host
   port: amqp
   role: normal
}
 
listener {
    host: 0.0.0.0
    port: 5677
    authenticatePeer: no
    saslMechanisms: ANONYMOUS
}

The router crashes trying to make a connection to some-host. The following is the router output
