[jira] [Created] (LOGCXX-517) Circular reference in ErrorHandlerTestCase

Robert Middleton created LOGCXX-517:
---------------------------------------

             Summary: 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


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.
