packet_.buffer() returns the clients current buffer (buffer[512]) as char*

This is the only place recvMessage is called
---------------
void CClient::recvHeader(const boost::system::error_code& error) {

    if(!error && packet_.decode()) {

        boost::asio::async_read(socket_,
                                boost::asio::buffer(packet_.buffer(), packet_.bodySize()),
                                boost::bind(&CClient::recvMessage, shared_from_this(), boost::asio::placeholders::error)
                                );
    } else {
        disconnect();
    }
}

In packet_.decode() the header is checked (through debugging I first notice the broken header before entering this function) and converted to the packet size and command, the size is used in packet_.bodySize(), which returns size_t *size
