 In my case I'm using a boost::shared_ptr<> containing maintaining a
 pointer to an abstract base class, this causes the following expression to
 naturally fail:

             // create a local value if Attribute is not unused_type
             typedef typename traits::container_value<Attribute>::type
                 value_type;
             value_type val = value_type();
