FreeBSD 5.0 and zsh 3.0.7 rare bug

FreeBSD 5.0 and zsh 3.0.7 rare bug

[Jeroen Ruigrok/Asmodai]

[Will: I cc:'d you since you're the MAINTAINER for the port]

For some weird reason every now and then my output got arsed.

I could do a ls -asl and get good output, then run a command, perhaps
interrupt it, and then try ls -asl again to get the output all mixed up.

After some inspection I came to the discovery that zsh sometimes out of
itself sets stty's icrnl option.  Which obviously messes up output.  I
have no idea what can cause this.

And since I don't have any tests which can reproduce it I cannot file
this as a bug.

The command I run may be a different command each time.  There's no
common program.  This particular case which let me find it was when
using truss.

Hope this helps somewhat,

Something I missed:

stty:

-icrnl

AND

-onlcr

Hm. I haven't seen this at all, and I've been running 3.0.7 forever
(note that 3.0.8 is out now).  Are you sure that the command you're
running doesn't fiddle with the tty settings and neglect to restore
them when you ^C?  I have "ttyctl -f" in my zshrc, which handles these
programs very nicely.
