Subject: gnu emacs 18.41 on iris [23].5 machines

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...
