9.5.1b2 rbtdb.c assertion failure

[Fr34k]

Hello,

Running 9.5.1b2 on Solaris9.
Crashed with this info:

Dec 31 13:04:25 named[308]: [ID 873579 daemon.crit] rbtdb.c:1482: REQUIRE((node)->references > 0) failed
Dec 31 13:04:25 named[308]: [ID 873579 daemon.crit] exiting (due to assertion failure)

[root at server root]# named -v
BIND 9.5.1b2

Below is what I found among BIND versions regarding rbtdb.c issues, but I don't see a match to what affected us.
Anyone have any ideas?

Thanks!
