             Summary: duplicate free: axis2_repos_listener and 
axis2_dep_engine_free when module load failed
                 Key: AXIS2C-1592
                 URL: https://issues.apache.org/jira/browse/AXIS2C-1592
             Project: Axis2-C
          Issue Type: Bug
          Components: core/deployment, core/engine
    Affects Versions: 1.7.0
            Reporter: Sebastian Brandt


When the loading of a module failes (a dll not found, axis2.xml not correct, 
etc) the engine and configuration are directly freed.
This results in duplicate free.
Ususally, this is not really a problem, as all ptrs in the structs that are 
freed twice are NULL, resulting in no additional problems.
Still, with MSVC and _CRTDBG_MAP_ALLOC, this leads to crashes.

Stack trace summary:
1) failed dep_engine_load_client calls repos_listener_free
2) failed dep_engine_load_client calls conf_free which calls dep_engine_free
3)  which calls repos_listener_free (again)
4) failed axis2_build_client_conf_ctx calls dep_engine_free (again).

Problem seems to be that the ownership is not agreed on between 
conf->dep_engine and dep_engine->conf.
