I removed the try catch in main and added a gdb backtrace

from cli.

Hi @inf265 ,

Thank you for using the library and reporting the issue. Although I don't have access to ARM to replicate the problem directly, I have some insights into what you've described.

The warning may be caused by the fact that the library is using:

    auto ch = GetChar();
    ...
    switch(ch) {
       case EOF: ... 

If, in your system, GetChar() returns an unsigned type and EOF has a negative value, it could trigger this warning. However, this would only affect the local session, not the remote one. Therefore, the abrupt closure of your telnet connection is likely not caused by this warning.

The exception in the main is thrown by Session::Disconnect():

    virtual void Disconnect()
    {
        socket.shutdown(asiolib::ip::tcp::socket::shutdown_both);
        socket.close();
    }

This method is called by the exit action of a CliTelnetSession. So, something is causing the telnet session to close, leading to the subsequent exception. Investigating the root cause of the telnet session closing soon after the connection is essential.

You can try using a newer version of the asio library (or try with Boost) if you're using an older one. Additionally, experimenting with different telnet clients or connection options might provide more insights.

Please keep me informed if you gather new information.
