I found the following bug in zsh 3.0.8 (I don't know if it exists in the
latest beta version, since i don't have it):
/home/nyh$ cat /tmp/z.z
echo $ZSH_VERSION
let 'a[3]=2'
let 'a[3]=2'
/home/nyh$ zsh /tmp/z.z
3.0.8
zsh: segmentation fault zsh /tmp/z.z
I don't know what's wrong: had an array already been defined, stuff like
let 'a[3]++' works. So why can't let 'a[3]=2' work? Strangely, the first
let command doesn't crash (but it doesn't set a[3]!), and only the second
one crashes zsh.
Thanks,
Nadav.

I can't reproduce the crash here. Further, a[3] gets set to 2 for me.
Does it happen to you with "zsh -f /tmp/z.z"? If not, we need to know
what your startup files are changing.
Can you generate a stack trace, e.g. with gdb or dbx, and send it to us?

My mind is slipping. There's a patch for this bug on SourceForge; go to
http://sourceforge.net/patch/?group_id=4068
for the complete list of 3.0.8 patches. The specific patch in question is:

It also happens with zsh -f. My system is Redhat 7.0, with the vanilla zsh:
/home/nyh$ uname -a
Linux tigger.haifa.radware.co.il 2.2.16-22 #2 Wed Oct 4 10:49:01 IDT 2000 i686 unknown
/home/nyh$ rpm -qf /bin/zsh
zsh-3.0.8-3

I'll try to compile zsh from sources to get a good stack-trace. So far I
only managed to get it from a non-stripped but non-"-g" binary I had lying
around, and got the following:
(gdb) r -f /tmp/z.z
Starting program: /usr/local/bin/zsh -f /tmp/z.z
3.0.8
Program received signal SIGSEGV, Segmentation fault.
0x806e0a5 in setiparam ()

rtld_fini=0x4000e264 <_dl_fini>, stack_end=0xbffffa3c)

If this is not enough information, I can compile it again with -g and
send you more information (and/or try to debug it myself).
Thanks!
Nadav.
