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 <at> gnu.org mailing list.

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

*Backtrace*:
Debugger entered--Lisp error: (wrong-type-argument window-live-p nil)
  select-window(nil nil)
  pop-to-buffer(#<buffer MultiOptimizer.h> other-window)
  compilation-goto-locus(#<marker at 2343 in *compilation*> #<marker at 786 in MultiOptimizer.h> nil)
  compilation-next-error-function(0 nil)
  next-error-internal()
  compile-goto-error(return)
  call-interactively(compile-goto-error nil nil)

the problem seems to be that line 1210 in window.el
    (setq new-window (display-buffer buffer other-window))
sets new-window to nil

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/share/emacs/23.0.60/etc/DEBUG for instructions.
