-----------------------------------
Summary: c++: memory leak in sasl examples
Key: PROTON-1115
URL: https://issues.apache.org/jira/browse/PROTON-1115
Project: Qpid Proton
Issue Type: Bug
Components: cpp-binding
Affects Versions: 0.12.0
Reporter: Alan Conway
Assignee: Cliff Jansen
The ssl C++ examples are leaking memory, valgrind output for for ssl follows,
the ssl_client_certs example has the same leak.
Putting printfs in ssl_domain_impl shows it is constructed 34 times and freed
21 times. This might explain the leak, but also seems like an unreasonably
large number of ssl_domains for such a simple test.
