[Boost-users] [serialization] Warning "type qualifier is meaningless on cast type" in extended_type_info_typeid.hpp

Hi,

When I compile code that uses the 1.48.0 serialization library with
icpc 12.3.174, I get this warning, along with screenfuls of
instantiation context:

/n/home00/pjonsson/include/boost/serialization/extended_type_info_typeid.hpp(134):
warning #191: type qualifier is meaningless on cast type
             static_cast<T const * const>(p)
                         ^

This is the offending code:

   virtual void destroy(void const * const p) const {
       boost::serialization::access::destroy(
           static_cast<T const * const>(p)
       );

The compiler is complaining (correctly, I think) that you can't
dictate whether something returned by value (here, the T const *) is
const or not. Changing the cast to:

 static_cast<T const *>(p)

makes the warning go away. Perhaps someone can make this change?

Regards,
