23.0.60; Crash when running as root

23.0.60; Crash when running as root

[Christian Faulhammer]

[-- Attachment #1: Type: text/plain, Size: 13450 bytes --]

Hi,

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Starting Emacs as root gives me a segmentation fault.  Current HEAD
from 29 May 2008 13:00 CEST.  Text mode works fine, also running as a
normal user.

I can't reproduce this.  Does it also crash with `emacs -Q'?

 I thought my root/.emacs was empty...but it wasn't.  It crashes with
the following statement:

(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.

nil :underline nil :slant normal :weight semi-bold :height 120 :width
normal :family "adobe-courier")))))

I wonder if this is related to the problem where Emacs locks up hard
when doing M-: (set-face-font 'default "Bitstream Vera Sans Mono-11")
RET.  That one has been present ever since the new font backend code was
merged to HEAD about a month ago.

That is the different bug, and I've just installed a fix.
