The problem is the use of file-exists-p (which tests if Elisp code can reach this file) instead of another function along the lines of file-accessible-directory-p, which checks whether the file name is reachable to C-level system primitives. "Unmodified" is not a real problem, although we might want to use some function to "canonicalize" the file name so as to increase the chances that the file is reachable to C-level system primitives. > either (1) by using the Magic File aware primitive expand-file-name expand-file-name is not the right function, even if in some cases it may happen to help. > 2. At the C-code level, there is a bug in that passing a > non-existent/invalid file path may cause the entire Emacs code to > crash. Right, this is the most serious of the two problems. Stefan
