Therefore I need to make a shared_ptr form the this pointer, in the constructor.

Why not use intrusive_ptr? Way back when, I wrote my own equivalent of that instead of using Boost.shared_ptr partly for this very reason (i.e., having to use smart pointers in constructors).

Ah, just read my Boost book on intrusive pointers and I think they would work. Not sure I will use for current issues, as have now written code for a factory mechanism (which appears to work!), but certainly worth knowing for the future. Thanks Rgds James
