Have you tried:

void Message::fromBinary( const std::string& data )
{
    std::istringstream ss(data, std::ios::binary);

    boost::archive::binary_iarchive ia(ss); //exception here

    ia >> *this;
}

The output side should be opened with "binary" as well. I'm surprised 
this didn't cause problems with 32bit as well.
