Disable ASLR stack gap.

Can you apply this patch and rebuild ntp, please.

If this is not possible (prefer you use the patch), add the following to
rc.conf.

ntpd_prepend=3D"/usr/bin/proccontrol -m aslr -s disable"

Applying the patch is preferred.

I haven't been watching the stable/12 branch but if this fixes the problem,
then someone has merged a prior version of ASLR stack gap code into the ker=
nel,
as this is no longer needed on 13 or 14 since ASLR is on something like ver=
sion
3 or 4 of the code, and wasn't needed on 12 since it didn't have ASLR.

If either of the above fixes this, it will tell us that some earlier versio=
n of
ASLR is in the 12.4 kernel.
