Hi,

the function is declared firstly without the inline keyword

        template <class T>
        clone_base * make_clone( T const & );

and the defined as

        template <class T>
        inline
        clone_base *
        make_clone( T const & x )
            {
            try
                {
                return new exception_clone<T>(x);
                }
            catch(
            std::bad_alloc & )
                {
                static bad_alloc_impl bad_alloc;
                return &bad_alloc;
                }
            catch(
            ... )
                {
                BOOST_ASSERT(0);
                return 0;
                }
            }
        }

I would try to add inline to the declaration.

        template <class T>
        inline clone_base * make_clone( T const & );
