 First, I coundn't make the test program sigsegv on my 5.2-RELEASE/i386 box.
 However, this following program does SIGSEGV on my box,
 
 #include <stdio.h>
 #include <sys/types.h>
 #include <pwd.h>
 
 int
 main(void)
 {
         struct passwd *pw;
 
         while ((pw = getpwent()) != NULL)
                 printf("%s\n", pw->pw_name);
         return 0;
 }
 
 This code segment is like some lines in top(1), so top(1) also
 SIGSEGV. As a notice, if you run this program or top(1) with root
 than you won't have SIGSEGV. My NIS server also supports passwd.adjunct.byname
 map (server is a FreeBSD box).
 
 I've tried the patch original attached, it's ok. If you want to ask me
 to do any test on my box, just tell me. Finally, I do consider this is 
 a serious bug, so please fix it ASAP, thanks.
