--------------------------------------
Hi Sebastian,
I had a similar issue... It was fixed in
https://issues.apache.org/jira/browse/AXIS2C-1611
Can you check the current revision to see if the issue is still there? (There
also seems to be same issue as AXIS2-1570)
> duplicate free: axis2_repos_listener and axis2_dep_engine 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.
