------------------------------+---------------------------------------------
 In Asio 1.4.6 / Boost 1.44, following program compiles when it shouldn't:

 {{{
 #include <boost/asio.hpp>
 #include <string>
 #include <vector>

 void handler(boost::system::error_code, std::size_t) {}

 int main()
 {
   boost::asio::io_service io_service;
   boost::asio::ip::tcp::socket sock(io_service);

   boost::asio::const_buffers_1 cb1(0, 0);
   sock.read_some(cb1);
   sock.async_read_some(cb1, handler);

   std::string s;
   sock.read_some(boost::asio::buffer(s));
   sock.async_read_some(boost::asio::buffer(s), handler);

   const std::vector<char> v;
   sock.read_some(boost::asio::buffer(v));
   sock.async_read_some(boost::asio::buffer(v), handler);
 }
 }}}
