#1137: Virtual destructor is missing

     Type:  Bugs                            |      Status:  new          
Milestone:  To Be Determined                |   Component:  serialization
  Version:  Boost 1.34.1                    |    Severity:  Problem      
 Keywords:  polymorphic archive destructor  |  
--------------------------------------------+-------------------------------
 The destructor of polymorphic_xml_oarchive gets never called when deleted
 through polymorphic_oarchive. I posted this to the users list and Robert
 Ramey already had a solution but it seems to not have made it into 1.34.1
 :-(

 The result of this is a memory leak and a missing </boost_serialization>
 tag at the end of the stringstream in the following example:

 {{{
 #include <iostream>
 #include <sstream>

 #include <boost/archive/polymorphic_oarchive.hpp>
 #include <boost/archive/polymorphic_xml_oarchive.hpp>

 void main(int argc, char** argv)
 {
         std::ostringstream buffer;

         boost::archive::polymorphic_oarchive* archive_interface;
         archive_interface = new
 boost::archive::polymorphic_xml_oarchive(buffer);
         delete archive_interface;

         buffer.flush();
         std::cout << buffer.str();
 }
 }}}
