7498	archive::binary_iarchive failure loading map<string,string>	kaedenn@…	Robert Ramey	"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

        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.
