Bind 9.5.1 crashes on reload

[jmorrisey71 at gmail.com]

When doing a RNDC reload with Bind 9.5.1 we are getting the following
error.
This only happens if we list more than one master name server IP.  If
we only have one IP in the "masters" statement it is fine.  If we have
more than one then everything seems to die.

Dec 29 15:00:06 tnamed[8957]: zone.c:5071: INSIST(zone->curmaster <
zone->masterscnt) failed
Dec 29 15:00:06 t179 named[8957]: exiting (due to assertion failure)


Anybody else have this problem?  Is there a work-a-round?

Thanks,
-Jake
