0. Extract the enclosed files to /tmp

1. Evaluate:

  (custom-set-variables
   '(ediff-skip-merge-regions-that-differ-from-default t)
  )
  (ediff "/tmp/x" "/tmp/y")
  
2. Hit the spacebar

Result: "You have killed a vital Ediff buffer---you must leave Ediff
now!"

This happens even with "emacs -q"

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:

0. Extract the enclosed files to /tmp

1. Evaluate:

  (custom-set-variables
   '(ediff-skip-merge-regions-that-differ-from-default t)
  )
  (ediff "/tmp/x" "/tmp/y")
  
2. Hit the spacebar

Result: "You have killed a vital Ediff buffer---you must leave Ediff
now!"

This happens even with "emacs -q"

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.60/etc/DEBUG for instructions.
