[Boost-users] Proper initialization of a boost::shared_ptr<> in a constructor

I am attempting to hunt down why I am getting a segmentation fault from
the boost::shared_ptr class. I know that it has to do with how I am
managing my shared pointers. That is creating and using them in
functions. I am reading the best practices web page and I have a
question about the best way to initialize a shared_ptr.

Normally I have a class like the following:

        class A {
        public:
        
                typedef boost::shared_ptr<A> ptr_t;
        
                A ( int input_value )
                : value ( input_value )
                {}
        
        private:
                int value;
        };

Which I will use in another place:

        class A_User {
        public:
        
                A_User ()
                : m_a_ptr ( new A() )
                {}
        
        private:
        
                A::ptr_t m_a_ptr;
        };
        
Is this the correct way to initialize the A::ptr_t held in the A_User
class in its constructor?
