3566	GCC 4.2 compiler warning in in basic_binary_oarchive.hpp:88	Thomas T. <boost-trac@…>	Robert Ramey	"Compiling our project with boost 1.40 on GCC 4.2 on OSX Snow Leopard with Xcode for x86_64 in debug mode produces the following warning for each of the translation units:

/opt/local/include/boost/archive/basic_binary_oarchive.hpp:88: warning: comparison between signed and unsigned integer expressions

This is the affected code (an assert):

    void save_override(const class_id_reference_type & t, int){
        // upto 32K classes
        assert(t.t <= boost::integer_traits<boost::uint_least32_t>::const_max);
        const boost::uint_least16_t x = t.t;
        * this->This() << x;
    }

Since the line where the error appears is the last line of the main function I suspect the problem is somehow triggered by destructor code. 

However as the template code error message is so unspecific and I am not familiar with the internals of the serialization implementation in boost, it is difficult for me to pinpoint what code using basic_binary_oarchive.hpp implicitly is causing this. There are several places where I have included binary_oarchive.hpp to enable serialization support for classes, but I cant track it down further."
