Robert,

I just now got home to try adding the two NVP wrappers you suggested.
The old problems went away, but there's a new set:

Merrill

Succ.h===========================================
#include "boost/serialization/nvp.hpp"
#include "boost/test/test_tools.hpp"

namespace MyNS {
class Succ {
        friend class Succ_Test;

private:
        size_t mInputIndex;
        bool mIsInbound;

    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive& ar, const unsigned int version) {
        ar & BOOST_SERIALIZATION_NVP(mInputIndex);
        ar & BOOST_SERIALIZATION_NVP(mIsInbound);
    }//serialize()

public:
        Succ() {} // needed by serialization
        Succ(size_t inputIndex, bool isInbound);
        virtual ~Succ();
        size_t inputIndex() const;
        bool isInbound() const;
};//Succ
}//MyNS

Succ_Test.cc===================================
#include <fstream>
#include "Succ.h"

#include "boost/archive/xml_iarchive.hpp"
#include "boost/archive/xml_oarchive.hpp"
#include "boost/test/test_tools.hpp"

using namespace std;

namespace MyNS {

class Succ_Test {
public:
    void run();
};//Succ_Test
//=============================================================================

void Succ_Test::run() {
        const char* archiveFile = "temp/Succ_archive.xml";
        size_t inputIndex = 65;
        bool   isInbound  = true;

        Succ* testObj_out = new Succ(inputIndex, isInbound);
    {
                // save data to archive
                ofstream outStream(archiveFile);
                boost::archive::xml_oarchive outArchive(outStream);

                // write class instance to archive
        outArchive << BOOST_SERIALIZATION_NVP(testObj_out);
        }	// archive and stream closed when destructors are called

        Succ* testObj_in;// = new Succ();
        {
                // create and open an archive for input
        ifstream inStream(archiveFile);
        boost::archive::xml_iarchive inArchive(inStream);
 
                // read class state from archive
        inArchive >> BOOST_SERIALIZATION_NVP(testObj_in);
        }   // archive and stream closed when destructors are called
        return;
}//run()
}//MyNS
