zsh exits suddenly.

zsh exits suddenly.

[Tanaka Akira]

I have a trouble that zsh exits as following.

akr@carbon% cd /usr/local/bin<^M>
akr@carbon% uname -a<^M>
SunOS carbon 4.1.4 1 sun4m
akr@carbon% zsh -c 'echo $ZSH_VERSION'<^M>
3.0.5-extended
akr@carbon% zsh -f<^M>
carbon% ls <^D>
zsh: do you wish to see all 848 possibilities? <^C>n
carbon% ls <^M>
akr@carbon% 

When typing <n> instead of <^C>, zsh works fine.
But I has habit that type <^C> frequently.

How do I make zsh to not exit after <^C>?

3.1.4 has the same problem.  This is exactly the bug that I described in
<http://www.zsh.org/mla/workers-1998/msg00372.html> (article 4037 if you
use the FTP archive (thanks, Geoff)) -- interrupting a read() with SIGINT
causes zsh to set lexstop to 1, which eventually causes the shell to exit.

I finally figured out where that's happening -- it's in ingetc(), which
is called from the SIGINT handler() via inerrflush().  However, I still
don't know how to fix the problem.

Why following fix is wrong?

Although I found that setopt ignoreeof prevents exiting zsh suddenly
in exchange for annoying errors...
