I usually HUP servers to force them to re-read their configuration
without forcing the server to restart.  I'm glad I found the earlier
commentary that HUPping radiusd is considered harmful.  I did it
myself when I was writing my first config last month, and ran across
the segfault, too.

Do you have in mind a favorite technique for signaling daemons that
the config files have changed?  HUP is a common way to do it, but I'm
sure there are other ways.
