 Here is an example of code which fails under windows with unhandled
 "access violation" exception when running on machine with two processors.

 Code was compiled with MS VS 8.0.

 #include "stdafx.h"
 #include <list>
 #include <string>
 #include <sstream>
 #include <boost\archive\text_iarchive.hpp>
 #include <boost\serialization\list.hpp>
 #include <atlsync.h>

 char Serialized[] = { 0x32, 0x32, 0x20, 0x73, 0x65, 0x72, 0x69, 0x61,
 0x6C, 0x69, 0x7A, 0x61, 0x74, 0x69, 0x6F, 0x6E, 0x3A, 0x3A, 0x61, 0x72,
