Double inheritance of enable_shared_from_this

Question

I have an object (Z) which derives from two other objects (A and B).

A and B both derive from enable_shared_from_this<>, respectively enable

Answer 1

Yep, your class will be derived from two distinct classes enable_shared_from_this and enable_shared_from_this, and have two different weak ref's

Trick from that answer allows to have one base class, because of virtual inheritance
