>From boost docs:
Q. Can an object create a weak_ptr to itself in its constructor?

A. No. A weak_ptr can only be created from a shared_ptr, and at object
construction time no shared_ptr to the object exists yet.

This is the problem I cannot seem to easily overcome in both the case of the
shared and weak ptr. It seems to work with a raw this pointer, but then I
cannot achieve my goal.
