With  1573, 1596 and 1598 applied to pre-2, not that these are likely relevant,
I get a segfault with the following

sun4% zsh -c xyzzy 
hello
zsh: 18399 segmentation fault  zsh -c xyzzy

where xyzzy is an autoloaded function containing

#!/usr/local/bin/zsh
. thing

and `thing' is a file reading

echo hello

Traceback attached.  None of the alloc_stackp related patches applied, since
they seemed all to be cosmetic.

On a related note, should the following not restore IFS?

sun4% IFS=@ set a@b@c@d; echo $IFS 
@

And finally, why doesn't this work?
sun4% local x=($(date))
zsh: not an identifier: 10 BST 1996)

I think this stops one saying IFS=@ local x=($(blaa)) using local, or
perhaps the even more vanilla typeset -t, as a way of making the
change to x permanent but restoring IFS.  Though maybe my whole notion
was flawed -- I was trying to split a command output into lines, but
the various expansions that happen after command substitution "corrupt"
the data.

Ah. Another core dump:
sun4% $(grep[TAB][TAB]
Program received signal SIGSEGV, Segmentation fault.
0x6ff8128c in _doprnt ()
#2  0x9afd0 in doexpandhist () at zle_tricky.c:3817
3817        DPUTS(useheap, "BUG: useheap in doexpandhist()");

Hmm. Time I went home.

Cheers
