> Key: PROTON-641
> URL: https://issues.apache.org/jira/browse/PROTON-641
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.8
> Reporter: Gordon Sim
> Assignee: Rafael H. Schloming
> Fix For: 0.8

> Attachments: proton_leak.cpp
>
>
> If the application doesn't call pn_link_close(), but calls
> on_session_close(), pn_connection_close(), then pn_transport_free() and
> pn_connection_free(), the pn_connection_t object appear to be leaked.
> Will attach reproducer. See also QPID-5951.
