Did you try this with 0.9.8o-4squeeze11?  I assume
0.9.8o-4squeeze7 didn't have a problem?

In any case I can't reproduce your problem.

As far as I know, ntp only uses openssl for autokey, but I also
don't have a setup with autokey.

I assume you removed the -u option?

How about starting it in gdb?  With the -n option it
should not fork, but I think gdb has an option to
follow the fork.
