I had done what you said, that is, instantiating the Repository singleton before calling its functions, during my first attempts... and this was the result:

int main()
{
        try
        {
                ObjectHandler::Repository repository;
                makeObject("Object1", "Foo");

                char tmp;
                std::cin >> tmp;
                return 0;
        }
        catch(...)
        {
                throw "Exception thrown!";
                return 1;
        }
}

That's the reason why I tried to not instantiate it before calling its method.
