Well, check autoconf's and automake's history of ca. the last 5 years. 
There have been a quite some patches been added to work around zsh issues ;)

One case I am currently aware about is this:

# cat script
SUBDIRS="a b  c"
list=${SUBDIRS}; for subdir in $list; do
echo $subdir
done

# /bin/bash script
a
b
c

Same result for dash and ksh, but for zsh:
# /bin/zsh script
a b  c

I was referring to the files I used in 
https://lists.fedoraproject.org/pipermail/devel/2014-October/202891.html

AFAICT so far, it fails because of behavioral difference between zsh and 
bash/ksh/dash outlined above (the "script" example).
