Having not gotten an answer to the query I set off to figure it out
myself. I have a plain pws-6 version. Perhaps I should try Bart's 8151 
but in any event let me tell you what I found out. 

During the config process I enabled: --enable-zsh-mem
--enable-zsh-secure-free --enable-zsh-mem-warning --enable-zsh-debug
and --enable-zsh-mem-debug. 

When I fired up zsh and attempted:

my_prompt_here> rpm -q My<TAB> 

I got this error/warning message: 'BUG: attempt to free already free
storage'

So I fired up gdb put a break at mem.c:977 and mem.c:1054 but for some 
reason I was unable to get it to repeat under gdb.. Well I ran out of
time and was happy with simply enabling --enable-zsh-mem and
--enable-zsh-secure-free. I wanted to get a stack trace when I got 
to the DPUTS warning message, but... 

I believe the error message I was seeing was coming from 977 but I
have not verified this. 

Thanks, in any event I will try the 8151 patch...
