Hi, I am having problem with the log4xx throwing an exception while calling logger->info() (it does not happen in Release version). I am using Visual Studio 2017 with the latest log4cxx 0.10.0. I have logger defined like this: log4cxx::LoggerPtr LCCService::logger(log4cxx::Logger::getLogger("LCCService")); .. then I try to log a message like this: o.str(""); o << "Initializing LCCService. ConfigPath=" << configFolderPath; logger->info(o.str().c_str()); That causes an exception: [cid:image001.jpg@01D3BB7C.BFFD1750] ... and the stack looks like this: [cid:image002.jpg@01D3BB7C.BFFD1750] Can anyone explained that?. I have to admit I have not been actively using C++ for some time. Regards, Janusz
