[CRASH] org-pretty-entities causes emacs to take 100% CPU

[CRASH] org-pretty-entities causes emacs to take 100% CPU

[Vladimir Alexiev]

1. Evaluate this:
(setq org-entities-user  ; name latex math-p html ascii latin1 utf8
      '(("ok" nil nil "ચ" "OK" "OK" "✔")
        ("nok" nil nil "ઞ" "NOK" "NOK" "✘")))
(setq org-pretty-entities t)    ; \ok -> ✔ in buffer

2. Put this in an org buffer
- \ok Deploy on x
- \nok Deploy on y
- \nok Use a hosted version 
It should display the UTF graphic chars above (checkmark and cross)

3. Step on the mark and move around
- left/right: ok
- up: gives error "Args out of range"
- down: causes emacs to take 100% CPU, no response, have to kill it
GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600) of 2010-11-10 on SHAN-PC

Not 100% sure the above is reproducible (got tired of having to kill my emacs),
but if someone takes up debugging, I'll give more precise steps

I followed your recipe above, and could not reproduce the error you
describe.  As a side note, I would suggest changing the
org-entities-user value to the following for correct html rendering (at
least using my browser -- chrome)

(setq org-entities-user  ; name latex math-p html ascii latin1 utf8
      '(("ok" nil nil "&#x2714;" "OK" "OK" "✔")
        ("nok" nil nil "&#x2718;" "NOK" "NOK" "✘")))

I've isolated it by running clean emacs (emacs -q) with this setup:

(setq org-entities-user	    ; name latex math-p html ascii latin1 utf8
      '(("ok" nil nil "<font color='green'>&#x2714;</font>" "OK" "OK" "✔")
        ("nok" nil nil "<font color='red'>&#x2718;</font>" "NOK" "NOK" "✘"))
      org-pretty-entities t)

And this small org file:

#+STARTUP:   showall indent
* Deployment Options
- \ok Deploy on

Observations:
- The crash DOES NOT happen with "noident"
- Moving up from the mark, I get this in *Messages*
  line-move-visual: Args out of range: 3, 3 
  (the number varies according to where the line is)
- it doesn't matter whether visual-line-mode is on or off

Thanks for the detailed report -- but I'm not able to reproduce this
with GNU Emacs 24.0.50.2 of 2011-02-15.

Can I get this from somewhere, built for W32/cygwin?
I got 24.0.50.1 from file Emacs24.BZR.102298.Win32.20101110.zip
from http://ourcomments.org/Emacs/DL/EmacsW32/EmacsCVS/unptch/ .
I looked there for a newer version, but there isn't one.

I cc Lennart, who can perhaps answer -- I'm not using windows.

I am now only uploading my patched version of Emacs+EmacsW32 since
there are now official binaries built from the trunk available. Please
see

  http://www.emacswiki.org/emacs/CategoryWThirtyTwo

BTW it has been quite a long time since I uploaded Emacs+EmacsW32
officially, but I did an inofficial upload yesterday. (I am not sure
how stable that is though I am using it myself.)
