    You can get the same when you overflow a buffer on a remote
    program [1] and execute a non-login shell. A simple workaround is to
    enter every command as
        do_some -thing ; echo :::
    and use the ":::" as a completion sign to the client program.

    Really you want to investigate the conditions in which your shell
    is running. Have a dig round in /proc for a problem shell and
    a normal one to compare it to.

    1. With permission of course.
