Comment (by Eric Müller <mueller@…>):

 I also encountered this issue, and overloading the friended
 `read_size_helper` (taking `basic_streambuf` as the first parameter) for
 `basic_streambuf_ref` (in `boost/asio/basic_streambuf.hpp`) might be a
 fix:

 {{{
 /// Adapts basic_streambuf to the dynamic buffer sequence type
 requirements.
 #if defined(GENERATING_DOCUMENTATION)
 template <typename Allocator = std::allocator<char> >
 #else
 template <typename Allocator>
 #endif
 class basic_streambuf_ref
 {
 // ...
 private:
   friend std::size_t read_size_helper(
       basic_streambuf_ref& sb, std::size_t max_size)
   {
     return read_size_helper(sb.sb_, max_size);
   }
 };
 }}}
