[jira] [Commented] (DISPATCH-1272) Router crashes when detach from
receiver and detach from broker arrive at the same time on a link route
[ https://issues.apache.org/jira/browse/DISPATCH-1272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16779581#comment-16779581 ]

Commit 8e94c5cf6f98083af3066b8cff2fd5aa0b176027 in qpid-dispatch's branch refs/heads/master from Ganesh Murthy
[ https://gitbox.apache.org/repos/asf?p=qpid-dispatch.git;h=8e94c5c ]
DISPATCH-1272 - Zeroed the qd_link->pn_link reference so there would be no attempt to send out a detach by CORE_link_detach if the outgoing pn_link has already been freed

> A receiver attaches to the router on a link routed address which is serviced by the *standalone* router via a route-container connection connected to the broker.
> When the receiver and the broker send detaches at the same time, the receiver side pn_link gets freed and the router tries to forward the detach received from the broker on to this freed pn_link and crashes.
