[Boost-users] Help with intrusive_ptr

Hello,
I use intrusive_ptr with a class that holds the refcount and I derive
from that class all my other classes.

class TObject {
 public :
int refcount ;

TObject () { refcount = 0;}

}
I have defined the intrusive_..._addref and _release  to increase and
decrease/delete that refcount and everything works good!

Anywhay sometimes I need to assign a derived object to another derived
object of the same type

instrusive_ptr <Derived> A = new Derived;
.
.
.
the problem:
*A = *Derived(constr parameters).
The point is that the refcount is assigned too (and becames 0)

How are instrusive_addref and _release supposed to be implemented ?

Any quick and clean solution for that ? I cannot write assignment
operator for every derived class because... there are a lot of members
:)

Really thanks!
Thomas
