 I have found it very useful to have access to the type names of shared
 objects for debugging purposes. May I suggest adding a type_info parameter
 to the hook functions:

 {{{
 void sp_scalar_constructor_hook( void * px, std::size_t size,
     std::type_info const & ti, void * pn );

 void sp_scalar_destructor_hook( void * px, std::size_t size,
     std::type_info const & ti, void * pn );
 }}}

 Then sp_counted_impl_p can call them like this:

 {{{
 explicit sp_counted_impl_p( X * px ): px_( px )
 {
 #if defined(BOOST_SP_ENABLE_DEBUG_HOOKS)
     boost::sp_scalar_constructor_hook( px, sizeof(X), typeid(X), this );
 #endif
 }

 virtual void dispose() // nothrow
 {
 #if defined(BOOST_SP_ENABLE_DEBUG_HOOKS)
     boost::sp_scalar_destructor_hook( px_, sizeof(X), typeid(X), this );
 #endif
     boost::checked_delete( px_ );
 }
 }}}

 Thanks!
