Summary: serialization of classes with overloaded operator & fails

Initial Comment:
the serialization of the following class fails to compile 
at line 363 in detail/iserializer.hpp, struct load_standard, method invoke, line
void * x = & const_cast<typex &>(t);

class wrapped_value
{
public:
        const int* operator & ()
        { // returns the address of the wrapped integer, which may noy be the same as the address of the instance
                return &a;
        }

        template <typename Archive>
        void serialize(Archive& ar, const unsigned version)
        {
                ar & a;
        }
private:
        int a;
};

due to the overloaded '&' operator getting the address of the instance fails. a proposed patch is
void * x = boost::addressof( const_cast<typex &>(t) );

which seems to compile and work correctly

cheers
