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.

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

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.

bug#1742: 23.0.60; ediff-skip-merge-regions-that-differ-from-default breaks simple ediffs

[Andrew Hyatt]

Did this end up getting fixed?  I can't reproduce this on Emacs 25.

I'll close this if I don't hear anything in a week or so.

Looks fixed in 24.5.1, FWIW.
