RTTI issue with non-polymorphic types in debug mode

[jlodos@…]

While serializing non-polymorphic types without RTTI in debug mode you get compiler warnings and execution crashes. In release mode everything works fine. This is because dynamic_cast is used for debugging purposes. The code is in smart_cast.hpp, starting in line 87:

                #if ! defined(NDEBUG)                               \
                || defined(__MWERKS__)
                    // do a checked dynamic cast
                    return cross::cast(u);
                #else

I believe the first line could be replaced with:

                #if (! defined(NDEBUG) && ! defined(BOOST_NO_RTTI) )  \

This solved the issue for me.
