Re: [Emacs-orgmode] Lockup in org-get-tags-at (4.32)

Hi Todd,

thanks for the report:

I can only reproduce the error if I have a level 2 entry in the first line of the archive file. I am guessing:

- You had this problem only with 4.32, not before?

Normally, when Org-mode creates the archive file, it makes sure that there are a level-one entry, so I guess you made this file in some other way?

4.32 calls org-get-tags-at during archiving, that is a mistake, will be fixed in 4.33.

Let me know if 4.33 does not fix the problem. In that case, can you make example files of your Org-mode file and the corresponding archive file to help me reproducing the problem?

- Carsten

I was trying to archive a TODO item and org-mode locked up.  I've
traced it down to org-get-tags-at which never returns. Below is a
stack trace with the "looping" portion marked.

--- End Loop
  outline-up-heading(1 t)
--- Loop
  org-set-tags(nil t)
  org-map-region(org-promote 1426 1480)

Hopefully, these lines won't get wrapped:

     1  (defun org-get-tags-at (&optional pos)
     2    "Get a list of all headline tags applicable at POS.
     3  POS defaults to point.  If tags are inherited, the list contains
     4  the targets in the same sequence as the headlines appear, i.e.
     5  the tags of the current headline come last."
     6    (interactive)
     7    (let (tags)
     8      (save-excursion
     9        (goto-char (or pos (point)))
    10        (save-match-data
    11          (org-back-to-heading t)
    12          (condition-case nil
    13              (while t
14 (if (looking-at "[^\r\n]+?:\\(address@hidden:]+\\):[ \t]*\\([\n\r]\\|\\'\\)")
    15                    (setq tags (append (org-split-string
    16                                        (org-match-string-no-properties 1) 
    17                                       tags)))
    18                (or org-use-tag-inheritance (error ""))
    19                (org-up-heading-all 1))
    20            (error nil))))
    21      (message "%s" tags)
    22      tags))

It is clearly stuck in the while loop between lines 13-19 but I'm not
sure why.  Does anyone else experience this behavior?
