26: Date: 04 May 87 23:53:11 PDT (Mon)

29: Aside from the SIGIOT, I know of only one bug, a real strange one:
30: I wrote a utimes interface, which copies elements from timevals
31: to utimbufs. This code is known good. The problem is that in
32: emacs, the utime doesn't seem to take effect (i.e. doesn't change the
33: dates at all) unless I call report_file_error *after* the utime returns!
34:
35: if (utime (name, &utb) < 0)
36: return;
37: else
38: /* XXX XXX XXX */
39: /* For some reason, if this is taken out, then the utime above breaks! */
40: /* (i.e. it doesn't set the time. This just makes no sense... */
41: /* Eric - May 4, 1987 */
42: report_file_error ("Worked just find\n", Qnil);
43:
44: Without any sort of debugger that works on emacs (I know... but I don't have
45: *time* right now to start with gdb), it was quite time consuming to track
46: it down to this.
47:
48: But since this code is only used for an optional 4th argument to one command
49: (copy-file), it would say that it is non-critical...
