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
