> Key: PROTON-1620
> URL: https://issues.apache.org/jira/browse/PROTON-1620
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.18.0
> Reporter: Cliff Jansen
> Priority: Critical
> Fix For: proton-c-0.18.0
>
>
> ssl_domain objects are semi-global.
> For example two connections simultaneously creating or releasing their own
> private pn_ssl_t objects may mess up the refcount of the shared
> pn_ssl_domain_t object leading to memory corruption or leaks.
> Windows schannel is further complicated by the OS internal refcounting of its
> security context thingies. That may get automatically solved by the above,
> or may require a separate JIRA to track. The same may apply to openssl.
