Hm. I can't reproduce this bug and my line complist.c:390 doesn't
access `amatches'.
So I have to ask: can someone tell me how to reproduce this with a
`zsh -f'?
Bye

} Hm. I can't reproduce this bug and my line complist.c:390 doesn't
} access `amatches'.
It does, but very indirectly. That line is (was, before your huge patch;
I don't know yet now):
for (i = (width ? width : mcols); i--; ) {
390 mtab[mx + mm + i] = mp;
mgtab[mx + mm + i] = g;
}
The value of `i' comes from `width' which comes a few call frames up from
`amatches->width', which is trash (a huge number).
} So I have to ask: can someone tell me how to reproduce this with a
} `zsh -f'?
The instructions that Alexandre gave were exactly what I did to produce
the stack trace.

I made zsh-3.1.6-bart-7 coredump with the following :
~ % zsh -f 19:47 #3
venus% mkdir empty
venus% cd empty
venus% zmodload complist
venus% touch {1..15} xxxxxxxxxxxxxxx
venus% bindkey "^[m" menu-select
venus% setopt listpacked
venus% foo <TAB>
1 11 13 15 3 5 7 9
10 12 14 2 4 6 8 xxxxxxxxxxxxxxx
venus% foo <M-m>
zsh: segmentation fault (core dumped) zsh -f
(<M-m> should be typed right after <TAB>)
I could reproduce this on Linux and Solaris.

Looks like the `amatches' global is garbage. Here's a stack trace (this is
after patches 8412 and 8413).
