I am trying to write a server and client that use a line-based text 
protocol for communication. It works rather well now, but there is some 
weird problem:<br><br>One of my messages loses the first 4 characters. (reproducible, but I don&#39;t do anything special in that one case, I think)<br>

<br>boost::asio::async_read_until is used to read the line into a boost::asio::streambuf<br>the socket is a boost::asio::local::stream_<div>protocol::socket<br><br>std::string msg;<br>std::istream is(&amp;buffer);<br>

std::getline(is, msg);<br>

<br>I looked at the buffer.size(), the size reported to the handler 
function and compared it to the length of the message, which looks 
consistant, so I don&#39;t assume that the read call read some characters 
over the \n. (but that would be the only logical explanation)<br>

<br>* there are no multiple read operations on the socket<br>* I reuse the same buffer for multiple async_read_until calls<br><br>Does
 anyone have a code snippet that can help me figure out what could be 
stuck and lost in the buffer, or where else the problem could be?</div>
