I edebug(use edebug-defun) some functions in file.el and then close file.el. When I open a new file, emacs aborts and show a buffer with edebug error(It can’t find the original source buffer to debug).
And I even can’t quit emacs because there are functions in kill-emacs-hook which try to open file and save data(such as recentf).
It will be good if there is a command to stop edebugging.
