FreeBSD child process die for root [SOLVED]

[Sagara Wijetunga]

   Dear all
   The issue was solved. It was a our side mistake. On a modification we
   made to libutils, we execute following line without checking whether
   the group is empty or not. In our case, it was empty, therefore,
   crashes:
   running = strdup(*(grp->gr_mem));
   So that now login, su and cron work well.
   Thank you for all those who helped us.
   Best regards
   Sagara
