Robert Middleton resolved LOGCXX-517.
-------------------------------------
Resolution: Fixed
> Circular reference in ErrorHandlerTestCase
> ------------------------------------------
>
> Key: LOGCXX-517
> URL: https://issues.apache.org/jira/browse/LOGCXX-517
> Project: Log4cxx
> Issue Type: Bug
> Reporter: Robert Middleton
> Assignee: Robert Middleton
> Priority: Major
> Fix For: 0.12.0
>
>
> For the smart pointer implementation, when GCC's sanitizers are
> enabled(fsanitize=leak), all tests pass except for the ErrorHandlerTestCase,
> which uses the FallbackErrorHandler.
>
> Likely this is due to a circular reference with the shared_ptrs.
>
> This may be cleanly done with an API-breaking change. The issue is that when
> using the DOM configurator, as soon as the XML file loads, it will attempt to
> open an invalid file, triggering the FallbackErrorHandler. The
> FallbackErrorHandler then removes the appender, and adds a new one. It seems
> that it should either propagate this error up, or replace the returned
> appender, instead of trying to replace the appender.
