Sorry, I can't see anything wrong with it.

  Robert,

  Yes the pointer is been initialized by NULL in the constructor of the class of that pointer.

  Thanks,
  Niranjan

  Do you know for  a fact that the pointer has been initialized?

    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.
    Niranjan
