OK.  Let me try again.

Your hex numbers are useless unless we can turn them into some reference to 
the code.

Can you try something like
    gdb <your ntpd>
    print /a <your hex number>

If that prints something useful, then we are on the right track.

Weird.  My usual problem is that it goes off when I don't want it to.

You might try strace to see if it gets to the kernel.  It won't cost much.  
There is the skeleton of a recipe in ntp_sandbox.c so you don't even have to 
read the man page.
  *  sudo strace -t -f -o<filename> <path-to-ntpd> <args>
