> I have a simple setup with a router, a sender and a receiver.
> The receiver is qpid-receiver from qpid-cpp-client-devel. The sender is a modified version of https://github.com/orpiske/msg-perf-tool, and I've pushed my modifications that made the router crash here: https://github.com/lulf/msg-perf-tool/tree/lulf/dispatch-crash-sender
> Using router built from master.
> Invoking the receiver: qpid-receive --broker 127.0.0.1:5674 --address amqp-test --ack-frequency 1 --messages 11111 --report-total -f --print-content false
> Invoking the sender: ./bin/mpt-sender -b amqp://127.0.0.1:5674/amqp-test -p 1 -d 1 -s 128
> The client might not behaving appropriately, so its entirely possible that I don't know what I'm doing! But I was thinking that the router should probably not crash due to misbehaving clients anyway. The core dump can be found here: http://lulf.no/stuff/qdrouterd_dispatch_387.core
