The strftime locale code attempts to read the locale cache even if the cache wasn't set up correctly. This leads to bogus output on your program's second (and subsequent) call to strftime(), if lookup failed. ... This patch fixes this.
An alternate fix appears below. --ado *** 7.62/strftime.c Fri Jun 15 13:00:07 2001 --- 7.63/strftime.c Fri Jun 15 13:00:07 2001 *************** *** 603,609 **** static const char locale_home[] = LOCALE_HOME; static const char lc_time[] = "LC_TIME"; static char * locale_buf; - static char locale_buf_C[] = "C"; int fd; int oldsun; /* "...ain't got nothin' to do..." */ --- 603,608 ---- *************** *** 664,671 **** goto bad_locale; bufsize = namesize + st.st_size; locale_buf = NULL; ! lbuf = (lbuf == NULL || lbuf == locale_buf_C) ? ! malloc(bufsize) : realloc(lbuf, bufsize); if (lbuf == NULL) goto bad_locale; (void) strcpy(lbuf, name); --- 663,669 ---- goto bad_locale; bufsize = namesize + st.st_size; locale_buf = NULL; ! lbuf = (lbuf == NULL) ? malloc(bufsize) : realloc(lbuf, bufsize); if (lbuf == NULL) goto bad_locale; (void) strcpy(lbuf, name); *************** *** 714,720 **** (void) close(fd); no_locale: localebuf = C_time_locale; ! locale_buf = locale_buf_C; return &localebuf; } #endif /* defined LOCALE_HOME */ --- 712,718 ---- (void) close(fd); no_locale: localebuf = C_time_locale; ! locale_buf = NULL; return &localebuf; } #endif /* defined LOCALE_HOME */
