The limit you should be looking for is the core file size, not file size,
(that's ulimit -c - or in csh terminology, coredumpsize) - and you also need
to remember that sudo might be deliberately setting that to 0 to prevent
any possibility of a core dump, testing its value in the shell isn't
definitive (you'd need a ktrace and check for setrlimit calls).
