Comment (by anonymous):

 Hello,

 {{{
 while (read_ec != boost::asio::error::eof);
 }}}

 error::eof is an enum value of type boost::asio::error::errc; in this
 context read_ec will be converted to bool and compared against the integer
 value of error::eof.

 Try to compare against {{{read_ec.value()}}} instead.
