Answer 1

Something to lookout for if you expose raw pointers from a dll interface. It forces you to use the shared dll CRT, memory allocated in one CRT cannot be deallocated in a different CRT. If you use the shared dll CRT in all your modules ( dll's & exe's ) then you are fine, they all share the same heap, if you dont you will be crossing CRT's and the world will meltdown.

Aside from that issue, I agree with the accepted answer. The creation factory probably shouldn't define ownership & lifecycle management for the client code.
