There are cases where the return value of ctl_getitem() is not directly checked
to make sure it's not NULL, but there are subsequent INSIST() checks that make
sure the return value is not NULL.  There are situations where this can happen,
and because the current code uses INSIST for safety checks this can cause ntpd
to abort.
