34 | Subject: gnu emacs 18.41 on iris [23].5 machines | |
35 | Date: 04 May 87 23:53:11 PDT (Mon) | |
36 | From: raible@orville.arpa | |

38 | Aside from the SIGIOT, I know of only one bug, a real strange one: | |
39 | I wrote a utimes interface, which copies elements from timevals | |
40 | to utimbufs. This code is known good. The problem is that in | |
41 | emacs, the utime doesn't seem to take effect (i.e. doesn't change the | |
42 | dates at all) unless I call report_file_error *after* the utime returns! | |
43 | ||
44 | if (utime (name, &utb) < 0) | |
45 | return; | |
46 | else | |
47 | /* XXX XXX XXX */ | |
48 | /* For some reason, if this is taken out, then the utime above breaks! */ | |
49 | /* (i.e. it doesn't set the time. This just makes no sense... */ | |
50 | /* Eric - May 4, 1987 */ | |
51 | report_file_error ("Worked just find\n", Qnil); | |
52 | ||
d8f6d720 | 53 | Without any sort of debugger that works on emacs (I know... but I dont have |
20c428fd JB |
54 | *time* right now to start with gdb), it was quite time consuming to track |
55 | it down to this. | |
56 | ||
57 | But since this code is only used for an optional 4th argument to one command | |
58 | (copy-file), it would say that it is non-critical... | |
