[Boost-users] [asio] Strange compilation error

Hi there I'm experiencing a strange compilation error that I cannot
resolve myself.

The following non-functionating triggers the error. I'm using VC2003
SP1. The error is due to the write() call.

template <class T > void sent( const T& object )
{
   std::ostringstream archive_stream;
   boost::archive::binary_oarchive archive( archive_stream );
   archive & object;

   std::string outbound_data = archive_stream.str();

   // Format the header.
   std::ostringstream header_stream;
   header_stream << std::setw( 8 )
                  << std::hex
                  << outbound_data.size();

   std::string outbound_header = header_stream.str();

   // Write the serialized data to the socket. We use "gather-write" to send
   // both the header and the data in a single write operation.
   std::vector<boost::asio::const_buffer> buffers;
   buffers.push_back(boost::asio::buffer(outbound_header));
   buffers.push_back(boost::asio::buffer(outbound_data));
   boost::asio::write( socket, buffers );
}

This is the verbose error message:
