/* Failure details:
At the top of the call stack,
    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.

m2 is empty when this exception is thrown, but it isn't always empty. Previous executions of this test
actually left data in m2, but that was with std::wstrings and not std::strings.
