[Bug 207560] Re: Emacs-snapshot segfaults with org-mode and linum.el

[Kees Cook]

** Description changed:

  Binary package hint: emacs-snapshot
  
  The Hardy version of emacs-snapshot has a segmentation fault when org-
  mode is used with (set-default-font "Monospace-8"), linum-mode, and
  certain org-mode files. I have attached the file which causes the crash.
  I would have liked to have used a less personal file (it is my computer-
  related todos), but it there does not seem to be much of a pattern to
  what causes a crash.
  
  The version of linum.el which I am using can be found here:
  
  http://stud4.tuwien.ac.at/~e0225855/linum/linum.el
  
  Steps to reproduce:
  
  1. Open emacs.
  2. Set the font to "Monospace-8"
  3. Open the org-mode file and collapse it so just the heading is showing (using tab).
  4. Load linum and run M-x linum-mode
  5. Try to expand the heading with tab.
  
  What happens:
  
  Emacs terminates with a segmentation fault, ever time.
  
  What should happen:
  
  The heading should expand to show the contents, or at the very least,
  emacs should die a bit more gracefully.
