This source block:

#+begin_src haskell :exports results 
nanmol=[1,1,3,2,1,2,3]
ncatmol=[2,1,2,1,2,1,2]
#+end_src
produces the error in the attached backtrace

Steps to reproduce:

1. emacs -Q -l init

with init being:

;;;; Org-mode
(add-to-list 'load-path "/home/rmason/.emacs.d/org-git/lisp")
(add-to-list 'load-path "/home/rmason/.emacs.d/org-git/contrib/lisp")
(add-to-list 'load-path "/home/rmason/.emacs.d/elpa/haskell-mode-20180601.143")
(org-babel-do-load-languages
 'org-babel-load-languages
 '((shell . t)
   (emacs-lisp . t)
   (haskell . t)
   ))

2. evaluste the source block

GNU Emacs 25.3.1 (i386-portbld-freebsd11.1, GTK+ Version 3.22.29) of 2018-04-26
Org mode version 9.1.13 (release_9.1.13-784-ged7d1d @
