Non-critical memory leak plugged

---

I have plugged a non-critical memory leak in MaraDNS 1.2.12.06.

I introduced this memleak in 1.2.12.06. This memleak will only be manifested if bind_star_handling has a value of 2. Since this is a feature that isn't even documented in 1.2.12.06, this memory leak is not critical enough for me to make a new release before the scheduled release of MaraDNS 1.2.12.07 on August 17, 2007.

Basically, if you need anally 100% RFC1034 section 4.3.3 compliance with star records, before setting bind_star_handling to two apply this patch:

maradns-1.2.12.06-star_collision_memleak.patch

1.3.05 also has this memory leak; the above patch *should* apply cleanly to the 1.3 branch of MaraDNS.

P.S. While 1.0.40 is available on on the official MaraDNS download page, it is also available on Sean's server.
