Subject Re: Exception when calling logger->info() method
Date Wed, 14 Mar 2018 02:26:51 GMT
Two quick thoughts:

   1. Have you ensure that the log4cxx dll and your application were
   compiled with the same version of cl.exe?  MS likes to change ABI
   compatibility between versions and odd bugs like this can come up when
   calling across the DLL boundary.
   2. Is there a reason you aren't using the LOG4CXX_INFO macro?  You
   should be able to simply use that macro to do what you are trying to do
   here but in an easier way.  Ex:
   LOG4CXX_INFO( logger, "Initializing LCCService. ConfigPath=" <<
   configFolderPath );

I don't know if the second point will do anything, but there could be an
issue with your call trying access a temporary variable on the stack.
