I wouldn't expect that property to be inherited to the child process
run by sudo.  It's the kind of thing normally set at exec time.  If
it works OK when you su, I would expect it to be OK with sudo.  At
one point sudo did disable coredumps in the child but that was
changed in sudo 1.6.3.  What do you see when you run:
    sudo -u news sh -c "ulimit -c"
