   I ended up having to NFS mount another machine so I would have enough disk

Looks like the new library took (I hope).  Nothing is complaining so I think
it's ok.

You can be more confident if you grab another recent ntp-dev tarball
(p259 is nice) and configure without --enable-c99-snprintf, build and
install it, and subject it to the ntpq -p every 5 seconds regime.


Ok, it didn't work using the new version of libc:

(gdb)

Are you sure you are using the new library?

I'm fairly certain. I did a make install after the libc compile, rebooted and then recompiled a new version of ntpd.
