Question

请帮我解决这个问题。我不确定这是否是一个重复的问题，但我找不到与我的情景相关的讨论。

我正在使用 Emacs 23 和 cedet 1.0.1 。当我在.emacs文件中配置自动完成时，每当我尝试从Emacs打开或保存.c文件时，我都会收到此错误。它挂了很长时间然后把这个错误扔进了* Messages * buffer。在缓冲区中还有一个长序列保存文件和写入行。

请帮我解决这个问题。

编辑：有关该问题的新更新

无意中我发现问题不是由于自动完成。这是由于我编写的一个Elisp函数在保存之前应用A代我的C代码。这是函数和我的c-mode-hook。

(defun astyle-this-buffer (pmin pmax)
  (interactive "r")
  (shell-command-on-region pmin pmax
                           "astyle" ;; add options here...
                           (current-buffer) t 
                           (get-buffer-create "*Astyle Errors*") t))

(defun ansi-c-mode-hook ()
  "turns off syntactic indentation and sets indent-region-function"
  (setq c-syntactic-indentation nil)
  ;;(setq indent-region-function 'astyle-this-buffer)
  (setq compile-command "bash cbuild.c")
  (setq enable-local-variables :all)
  (global-set-key (kbd "C-c .te") '(lambda ()
                                      (interactive)
                                      (run-command 'test-command)))
  (global-set-key (kbd "C-c .cs") '(lambda ()
                                      (interactive)
                                      (run-command 'check-code-style))))

如果我取消注释行(setq indent-region-function 'astyle-this-buffer)，则会在保存时出现上述错误。那么函数astyle-this-buffer有什么问题？我记得的是我从stackoverflow.com的一些帖子中获取了它。
