Apologies for the vagueness, I'm traveling at the moment and didn't dig into
this enough fully.
Here's the function that raised the error:
(defun haskell-indentation-find-indentations ()
(let ((ppss (syntax-ppss)))
(cond
((nth 3 ppss)
(haskell-indentation-first-indentation))
((nth 4 ppss)
(if (save-excursion
(and (skip-syntax-forward "-")
(eolp)
(not (> (forward-line 1) 0))
(not (nth 4 (syntax-ppss)))))
(haskell-indentation-parse-to-indentations)
(haskell-indentation-first-indentation)))
(t
(haskell-indentation-parse-to-indentations)))))
So it would seem that the byte-compiled file is referencing the variable. When
I re-evaluate the file this definition is contained in, the error goes away.
Unfortunate, but easily solved. And I don't believe we guarantee .elc
compatibility between major releases.
