Justin Ross commented on PROTON-893:
------------------------------------
I get a different bad result from the session_close_con.py example. It does an
infinite session begin and end.

> Calling session.close() on non-active session causes client segfault
> --------------------------------------------------------------------
>
> Key: PROTON-893
> URL: https://issues.apache.org/jira/browse/PROTON-893
> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Affects Versions: 0.9.1
> Environment: packages:
> qpid-proton-c-0.9-3
> qpid-proton-c-devel-0.9-3
> python-qpid-proton-0.9-3
> Reporter: Petr Matousek
> Assignee: Justin Ross
> Priority: Minor
> Labels: crash, reproducer
> Fix For: proton-c-0.18.0
>
> Attachments: session_close_con.py, session_close_ssn.py,
> stacktrace.txt
>
>
> Calling the session.close() on non-active session causes client segfault (see
> the attached reproducer session_close_con.py).
> Moreover calling connection.session().close() causes client seqfault even if
> the session shall be in active state (see the attached reproducer
> session_close_ssn.py).
