Thank you, Richard. Good suggestion. However, I forgot to show the callee represented by macro LOG4CXX_INFO: It takes a string& argument. The 4 byte shift indicates, that std::string is of a different definition in calling app and dll. This should not be the case, in particular, as both had been compiled with default debug settings. In particular, what I have done now, was to explicitly set _ITERATOR_DEBUG_LEVEL=2 (an often stated reason for a diverging std::string implementation) when compiling the dll.
