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.

Apparently this not the case. I tested in gdb and boost::asio::error::eof is first converted to an error_code which is then compared to read_ec.
