You're using 5.0.2, which is four years old.  We've fixed this bug in
5.2 last year:

    commit 83a175795a444e8169fcb592a110d4d15a09b907
    Author: Peter Stephenson <pws@zsh.org>
    Date:   Tue Oct 6 09:28:07 2015 +0100
    
        36780: Fix crash in ksh mode with -n and $HOME.
        
        If home variable is NULL ensure HOME is unset.

Current master does not have the problem:

% ARGV0=ksh Src/zsh -fn =(<<<$'#!/bin/sh\necho $HOME\n') 
% 

Thanks for the bug report and the patch.

Cheers,

Daniel
