How to reproduce:
emacs -Q --eval '(progn
(require (quote org))
(require (quote hideif))
(add-hook (quote c-mode-hook) (quote hide-ifdef-mode))
(setq hide-ifdef-initially t)
(setq hide-ifdef-shadow t))'
Then edit an org file that contains a src block for C.
#+begin_src C
void foo() { }
#+end_src
C-c ' on that src block will echo an error message:
Initialization fails with: "Wrong type argument: stringp, nil"
Since C-c ' opens a special buffer that hasn't a file related, the
`buffer-file-name' will return `nil'. It's the second parameter of
`string-match' in `hide-ifdef-gets'.
The definition of `hide-ifdef-guts` follows.
(defun hide-ifdef-guts ()
"Does most of the work of `hide-ifdefs'.
It does not do the work that's pointless to redo on a recursive entry."
;; (message "hide-ifdef-guts")
(save-excursion
(let* ((case-fold-search t) ; Ignore case for `hide-ifdef-header-regexp'
(expand-header (and hide-ifdef-expand-reinclusion-protection
(string-match hide-ifdef-header-regexp
(buffer-file-name))
(zerop hif-recurse-level)))
(case-fold-search nil)
min max)
(goto-char (point-min))
(setf min (point))
(cl-loop do
(setf max (hif-find-any-ifX))
(hif-add-new-defines min max)
(if max
(hif-possibly-hide expand-header))
(setf min (point))
while max))))
