6730	error reading archive created by old version when it contains pointer	d s m a l l @…	Robert Ramey	"Problem is similar to ticket 4660.  Fwiw we just discovered a gap
in our unit tests. :(

Code below contains our local fix.  Note that we only have used
lib ver 3 and lib ver 5 and that this is the reason the fix only 
targets those versions.

One last word, I checked the latest code ( 1.49 ) and it seems to
contain the same flaw as 1.45.

{{{
    void load_override(class_id_type & t, int version){
        library_version_type lvt = this->get_library_version();
        if(boost::archive::library_version_type(7) < lvt){
            this->detail_common_iarchive::load_override(t, version);
        }
        else
        if(boost::archive::library_version_type(6) < lvt){
            int_least16_t x=0;
            * this->This() >> x;
            t = boost::archive::class_id_type(x);
        }
        else
        if(boost::archive::library_version_type(3) == lvt || boost::archive::library_version_type(5) == lvt ){
#pragma message( ""CTMS fix for serialization bug ( lack of backwards compatability ) introduced by boost 1.45."" )
            int_least16_t  x=0;
            * this->This() >> x;
            t = boost::archive::class_id_type(x);
        }
        else{
            int x=0;
            * this->This() >> x;
            t = boost::archive::class_id_type(x);
        }
    }
