Re: [Boost-users] [boost::shared_ptr] Memory is not freed

I wish I could include the code in this email, but it is very long  and complicated. Therefore, I am kindly asking you to guess what might have been wrong with the boost:shared_ptr. Could you think of any scenarios that would cause the observed bahavior?

Circular references. If A has shared_ptr to B, and B has shared_ptr to A, they both will never be release. To break such circular referencing, you should use weak_ptr for one direction.
