Emmanuel Bourg commented on QPID-2482:
--------------------------------------
Sorry for the false report, I misunderstood the behavior of the example. I saw
the messages twice and assumed that was the same issue reported here. But in
this case there is one queue with several bindings, whereas the example uses
several queues with only one binding.
Maybe changing the example to use only one queue would avoid the confusion.

> Key: QPID-2482
> URL: https://issues.apache.org/jira/browse/QPID-2482
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Environment: Linux
> Reporter: Ken Giusti
> Assignee: Ken Giusti
>
> As per Gordon's description:
> If a given queue is bound to a topic exchange with multiple bindings, a
> message sent to that exchange will result in a copy being enqueued for each
> binding that matches. This is incorrect - each message should be enqueued
> once if there is any binding to the queue that matches it.
> Steps to Reproduce:
> 1. create queue
> 2. bind it to amq.topic with two distinct bindings (e.g. red.* and *.herring)
> 3. send amq.topic a message whose routing key matches both patterns (e.g.
> "red.herring")
> 4. check the queue
> Actual results:
> The message is enqueued on the queue twice.
> Expected results:
> The message should only be enqueued on the queue once.
