tty settings being corrupted

[martin.ebourne@arcordia.com]

If I perform the following sequence:


% stty
speed 38400 baud; evenp hupcl
rows = 24; columns = 80; ypixels = 316; xpixels = 499;
erase = ^h; swtch = <undef>;
-brkint -inpck -istrip
crt iexten

% zsh -f       [ Type ctrl-D immediately after enter such that the shell gets it before printing the prompt]

% stty
speed 38400 baud; evenp hupcl
rows = 24; columns = 80; ypixels = 316; xpixels = 499;
quit = <undef>; erase = ^h; eof = ^a; swtch = <undef>; susp = <undef>; dsusp = <undef>; flush = <undef>; lnext = <undef>;
-brkint -inpck -istrip inlcr
crt iexten

% echo $ZSH_VERSION
4.0.2

% uname -a
SunOS gdd-odybin2.uk.jpmorgan.com 5.6 Generic_111435-01 sun4u sparc SUNW,Ultra-Enterprise-10000

Here the shell has corrupted the tty settings simply by running it and quitting before entering the line editor. Obviously ctrl-D after the prompt has
 been printed is fine.

Any ideas what is happening here? I could use ttyctl -f but I consider that a bit a brute force solution.

Cheers,

Martin.
