I see the same thing on an 8.1 Indy. I think it's caused by the way
tcsh is invoked by session_gate, i.e. with .logout on standard input.
(stty operates on descriptor 0). You see the same error if you run
tcsh with input redirected; it's questionable for it to set prompt in
this case, but csh also does it.
Anyone know why the stty is done in cshrc? The code reads:
# Have no better way to do this at the moment.
if ($?prompt) then
stty sane intr ^C
endif
(The Sun cshrc doesn't do this...).
Assuming we do need the stty, probably the best thing to do is add a
test here for the standard input being a terminal, using 'tty -s'.
I'll add this if people agree...
