Re: [Boost-users] [Serialization] Strange crash with binary_iarchive

I'd like to add the following to the above:

I tried adding the simple serialization code based on the boost site example
to my app and it crashes for both writing and reading the binary archive:

#include <string>
#include <vector>
#include <fstream>
#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/serialization/base_object.hpp>
using namespace std;

class gps_position
{
private:
    friend class boost::serialization::access;
    // When the class Archive corresponds to an output archive, the
    // & operator is defined similar to <<.  Likewise, when the class
Archive
    // is a type of input archive the & operator is defined similar to >>.
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        ar & degrees;
        ar & minutes;
        ar & seconds;
    for(int i = 0; i < 10; i++) {
        ar & data[i];
    }
    }
    int degrees;
    int minutes;
    float seconds;
    double* data;
public:
    gps_position(){};
    gps_position(int d, int m, float s) :
        degrees(d), minutes(m), seconds(s)
    {
    data = new double[10];
    for(int i = 0; i < 10; i++) {
        data[i] = i*0.1;
    }
    }
};

void boost2()
{
    cout << "writing archive..." << endl;
    std::ofstream bofs("gps.bin", std::ios::binary);

    // create class instance
    const gps_position g2(36, 60, 24.567f);
    boost::archive::binary_oarchive oa(bofs);
    oa << g2;

    cout << "reading archive..." << endl;
    gps_position newg;
    // create and open an archive for input
    std::ifstream ifs("gps.bin", std::ios::binary);
    boost::archive::binary_iarchive ia(ifs);
    // read class state from archive
    ia >> newg;

    cout << "done." << endl;
}

// calling boost2()
 crashes - stack shown below:
