        !            28:   Aside from the SIGIOT, I know of only one bug, a real strange one:
        !            29:   I wrote a utimes interface, which copies elements from timevals
        !            30:   to utimbufs. This code is known good.  The problem is that in
        !            31:   emacs, the utime doesn't seem to take effect (i.e. doesn't change the
        !            32:   dates at all) unless I call report_file_error *after* the utime returns!
        !            33: 
        !            34:     if (utime (name, &utb) < 0)

        !            40:       /* Eric - May 4, 1987 */

        !            42: 
        !            43:   Without any sort of debugger that works on emacs (I know... but I don't have
        !            44:   *time* right now to start with gdb), it was quite time consuming to track
        !            45:   it down to this.
        !            46: 
        !            47:   But since this code is only used for an optional 4th argument to one command
        !            48:   (copy-file), it would say that it is non-critical...
