placement new to defer to a different constructor

Question

Is this safe? I\'m not using any virtual functions in my actual implementation, but I\'m tempted to believe that even if I was, it would still be safe.

Answer 1

One worry I have is if Foo uses multiple inheritance you'll need to cast the this pointer to the most base class first. Othewise if the the this is offset (sometimes happens in multiple inheritance) it'll construct at the wrong address.
