2217	serialization 1.36.0 extended_type_info exit issue(s)	timothysc@…	Robert Ramey	"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.

//////////////////////////// snippet: ////////////////////////////
BOOST_AUTO_TEST_CASE( MyTestClass_Serialization )

    // MyTestClass is an uses intrusive serialization (You could use any object)

    boost::shared_ptr<MyTestClass> outtie ( new MyTestClass() );
    boost::shared_ptr<MyTestClass> innie;
   
    std::ofstream os( ""MyTestClass_Serialization.xml"", std::ios_base::out );
    boost::archive::xml_oarchive xmlao(os);
    xmlao << boost::serialization::make_nvp( ""testKey"", outtie );
    os.close();      

    std::ifstream is( ""MyTestClass_Serialization.xml"", std::ios_base::in );
    boost::archive::xml_iarchive xmlai( is );
    xmlai >>boost::serialization::make_nvp( ""testKey"", innie );
    is.close();
  
    BOOST_CHECK_NO_THROW();
