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 ()

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!
