Re: [Boost-users] serialization 1.36.0 extended_type_info exit issue(s)

From: Robert Ramey (ramey_at_[hidden])

More likely a bug introduced by recent improvements in handling automatic registering/deregistering.

Please make a small test case (below isn't complete) along with information about compiler, os, 
etc and open up a TRAK item.

  Folks, 

      I'm running some serialization unit-tests which pass with flying colors under 1.35.0 and earlier, however they seg-fault on exit when run through 1.36.0.  

      The error appears to deal with destruction of extended_type_info_typeid objects, and *only* manifests itself when I load an archive through a shared_ptr<T>.  The load will appear to function properly, then on exit of the application, <<Death>>.  This occurs even if I remove BOOST_CLASS_EXPORT && BOOST_CLASS_TYPE_INFO as the shared_ptr is to the derived element, and I'm not testing through a base. 

      My lastest guess is that I may be missing some #define BOOST_SOME_MAGIC_NEW_OPTION

      std::ofstream os( "MyTestClass_Serialization.xml", std::ios_base::out );
      my_pack< MyTestClass >( os, outtie );
      os.close();       

      std::ifstream is( "MyTestClass_Serialization.xml", std::ios_base::in );
      my_unpack< MyTestClass >( is, innie );
      is.close();
     
      BOOST_CHECK_NO_THROW();
  }
