segfault in opensuse-11.2 latest CVS sources

[Vin Shelton]

Greetings!

I've just switched over to OpenSUSE 11.2 (from kubuntu) and I'm
getting a crash in the when trying to match usernames for chown.
Here's a recipe:

zsh -f
autoload -U compinit
compinit -u
chown a<TAB>

kaboom

It looks like it's crashing in setpwent().  The code in hashtable.c
seems pretty straightforward.  Have I misconfigured my system somehow?

Anyway, here's the backtrace:

Yes.  Or your vendor provided a buggy system.

Look at /etc/nsswitch.conf.

Are you using NIS or something, so that you need libnss_compat?  If not,
I'd change s/compat/files/g in the values in /etc/nsswitch.conf and
remove the _compat entries.  One less library probed in every binary
doing any kind of name resolution, one less thing to go wrong.

If you're getting an abort() call inside free() then free() has been
passed a bad memory location, so if this is happening inside setpwent()
then something's very wrong down there.  Perhaps you've removed
nsswitch.conf or you've removed some of its contents.  Perhaps there's a
major platform bug.
