     Type:  Bugs                         |      Status:  new          
Milestone:  To Be Determined             |   Component:  serialization
  Version:  Boost 1.51.0                 |    Severity:  Showstopper  
 Keywords:  binary serialize map string  |  
-----------------------------------------+----------------------------------
 I create two std::map<std::string, std::string> instances, one of which
 having two dozen contents, the other default-initialized. I serialize the
 former using boost::archive::binary_oarchive and load it into the latter
 using boost::archive::binary_iarchive.


 {{{
 // This Win32-specific test creates a std::map from strings to strings and
 // then serializes it to a file. We then attempt to desearialize from that
 // file. On boost_1_45_0 and boost_1_51_0 for Win32 this testcase fails on
 // our company's secondary build machine.

 {{{
 /*
 At the top of the call stack (see attachment for context),
     std::streamsize s = static_cast<std::streamsize>(count /
 sizeof(Elem));
     std::streamsize scount = m_sb.sgetn(
         static_cast<Elem *>(address),
         s
     );
     if(scount != s)
         boost::serialization::throw_exception(
             archive_exception(archive_exception::input_stream_error)
         );
 `scount` is 0, `s` is 8. It's trying to load a size_type, presumably for a
 string length or a map length.
