Hi all,

Boost:1.38.0
compiler:gcc4.1.1

I am trying to serialize and deserialize a pointer to the class, but ended with the segmentation fault, Is that the null pointer serialization gives the segmentation fault?. I read in document that, library will maintain the Null pointer. if not how can i serialize? ,any docs or related refference is a;so acceptable. Thanks in advance....

one more thing: what -1 in archive(text_archive) indicates?

Example
------------

#include <fstream>
   #include "boost/archive/text_iarchive.hpp"
   #include "boost/archive/text_oarchive.hpp"
#include "boost/serialization/access.hpp"
#include "boost/serialization/assume_abstract.hpp"

class Dkpt
{

public:

friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int file_version)
{
     (void) file_version;
          ar & data_;
          ar & b_i;
          ar & f_er;
          ar & pa_er;
          ar & ct_c;
}

private:

uint8_t data_;
bool b_i;
bool f_er;
bool pa_er;
bool ct_c;

};

----
class RB : public RM
{
public:

virtual void checkpoint_save(boost::archive::text_oarchive & oa)
{
     oa & dr;
}

virtual void checkpoint_retrive(boost::archive::text_iarchive & ia)
{
     ia & dr;
}

private:

Dkpt* dr;

;}

Thanks.
