Hi zsh,
The following appears to be a bug:
$ zsh --version
zsh 5.9 (x86_64-pc-linux-gnu)
$ uname -r
6.8.7-arch1-1
$ reset
$ STTY={-icanon,-echo} xxd -ps -l3 # input Ctrl-J, Ctrl-M, Return
0a0a0a
$ STTY={-icanon,-echo,icrnl,inlcr} xxd -ps -l3 # input Ctrl-J, Ctrl-M, Return
0d0a0a
$ STTY={-icanon,-echo} xxd -ps -l3 # input Ctrl-J, Ctrl-M, Return
0d0a0a
The STTY parameter description in zshparam(1):
> If this parameter is set in a command's environment, the shell runs the stty
> command with the value of this parameter as arguments in order to set up the

But as you can see, INLCR was not reset.
Cheers,
Ronan

I can't reproduce with the current git master.

The only way I can something similar happen is by running the last two xxd
commands without allowing a prompt to be printed in between. Zsh only
resets the terminal at each new prompt, not at every command exit.
