>                 Key: PROTON-2959
>                 URL: https://issues.apache.org/jira/browse/PROTON-2959
>             Project: Qpid Proton
>          Issue Type: Bug
>          Components: python-binding
>            Reporter: Andrew Stitcher
>            Assignee: Andrew Stitcher
>            Priority: Major
>
> Create a Transport object, then create a SSL or SASL object from it then 
> destroy the Transport object - either directly with del or by setting the 
> variable to None in versions of python that collect promptly.
> At this point using any SASL/SSL API that calls into the C level API will 
> potentially crash as it's accessing freed memory.
