Thank you for your answer.

I know that intrusive_ptr is not documented yet.

But in documentation of weak_ptr is written that when all shared_ptr are 
destroyed all weak_ptr are set to 0. And it of course works in that style for 
normal shared pointer.

But when I am using weak_ptr with intrusive_ptr it know works like normal 
pointer? 

I think I missed something. Is it bug or feature?

Thank yo for your answer.
