I was trying to look at the CaveClientApp segfault on exit, so compiled the code with -fsanitize=address, this highlighted that the global variable Credits defined in CredisWindow.hpp is linked in to the main executable CaveClientApp and libCaveClient.so

Anyway, probably not the error I was looking for but felt like it needed logging.
