+  Subject: gnu emacs 18.41 on iris [23].5 machines
+  Date: 04 May 87 23:53:11 PDT (Mon)
+  From: raible@orville.arpa
+
+  Aside from the SIGIOT, I know of only one bug, a real strange one:
+  I wrote a utimes interface, which copies elements from timevals
+  to utimbufs. This code is known good.  The problem is that in
+  emacs, the utime doesn't seem to take effect (i.e. doesn't change the
+  dates at all) unless I call report_file_error *after* the utime returns!
+
+    if (utime (name, &utb) < 0)
+      return;
+    else
+      /* XXX XXX XXX */
+      /* For some reason, if this is taken out, then the utime above breaks! */
+      /* (i.e. it doesn't set the time. This just makes no sense... */
+      /* Eric - May 4, 1987 */
+      report_file_error ("Worked just find\n", Qnil);
+
+  Without any sort of debugger that works on emacs (I know... but I don't have
+  *time* right now to start with gdb), it was quite time consuming to track
+  it down to this.
+
+  But since this code is only used for an optional 4th argument to one command
+  (copy-file), it would say that it is non-critical...
