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.
