>Organization:
The FreeBSD Project (Japan)

FreeBSD xxx 4.4-STABLE FreeBSD 4.4-STABLE #2: Tue Dec 4 13:42:07 JST 2001 root@xxx:/path/to/src/sys/ XXX i386
>Description:
locate command assumes that a database file is perfect,
but it dumps a core file with a broken database.
I don't think it should not dump a core file
even if it uses a broken database.
>How-To-Repeat:
% cat /var/db/locate.db ~/somefile >locate.db
% locate -d ./locate.db word
(some search results)
Segmentation fault (core dumped)
>Fix:
I think a check routine is needed in locate/fastfind.c near...:
290 if (*s == cc
291 #ifdef FF_ICASE
292 || TOLOWER(*s) == cc
293 #endif /* FF_ICASE */
294 ) { /* fast first char check */
295 for (p = patend - 1, q = s - 1; *p != '\0';
296 p--, q--)
297 if (*q != *p
298 #ifdef FF_ICASE
299 && TOLOWER(*q) != *p
