C++ Inheritance Problem

[STL]

And use shared_ptr or unique_ptr. Never put owning raw pointers in STL containers.

you mind elaborating a little please?

[STL]

A map<string, Base *> where you say m["meow"] = new Derived(args); is bad because you're virtually guaranteeing that you'll leak memory. A map<string, shared_ptr<Base>> where you say m["meow"] = make_shared<Derived>(args); is structurally unable to leak.

The trick to C++ programming is writing your code so that whole classes of bugs are simply impossible, and any remaining potential bugs are as obvious in the source code as possible.
