zsh bug?

zsh bug?

[possibilitybox]

I was using zsh in screen, in an aterm (in x, obviously.), and
suddenly I lost tab-completion ability and the ability to run any
command except built-ins.  When I tried to log back in I received an
error about not being able to cd to my home directory, I may still
have these errors in an irc log.  Root could still log in, and once
logged in as root (using the same shell) i could not su to my user; I
received an error about not having permissions to execute /bin/zsh. 
Re-installing zsh from the slackware package fixed all my problems,
but I figured that this error should be reported.  (and I'm interested
myself to know how that happened.)

Did you at some point remove read or execute access to /?  That's the
only way I can think of that would have denied access to all
executables and your home directory at once.  I can't imagine how zsh
could be responsible.

zsh bug?

[Michael Vanier]

Hi all,

I've just started using zsh and I can't seem to get it not to report when I
receive mail.  I've tried doing "unsetopt mailwarning" but that seems to
have no effect.  This is on a Solaris 2.3 system.  I suppose I could set
the MAILCHECK variable to some absurdly high level, but that's just a
kludge.  Any suggestions?

Thanks,

Mike

Panic not!

I just found out that it is a simple bug in ping.  There are patches 
available for it.

I tried it on an OSF box. The error I got was:


        ping: illegal packet size


When I try in using ZSH 2.6-beta16 on SunOS 4.1.3 (not _U1), I only get:


        zsh: segmentation fault  ping -s www.americanexpress.com

This is not a zsh bug.  ping dumps core,  and zsh prints:

zsh: 336 segmentation fault (core dumped)  /usr/sbin/ping -s www.americanexpress.com

The zsh: means that it was zsh which printed the message but at the end of the
message you can see what caused the coredump.

Of course Linux ping works fine.  It's time to upgrade to SparcLinux :-).

zsh bug?

[Tom Kaczmarski]

When I run the following command:

ping -s www.americanexpress.com

the child zsh dumps core and reports a fragmentation error.

To my knowledge, this only happens with this particular address.

This happens on both Solaris 2.5i SPARC version, and SunOS 4.1.3_U1.  I also 
tried to replicate this error on an AIX box, but ping takes a little 
different flags.  I wish I had access to another OS to verify that 
behavior.  Could someone try it on a different OS like Irix, OSF, HP-UX, 
BSD, and Linux?

Thanx
Tom
