It looks like CVE-2010-3613
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-3613> <http://www.isc.org/software/bind/advisories/cve-2010-3613> but:

Strange because it should not be vulnerable. May be a similar
unreported bug? Samer Khattab and nicku just reported a very similar bug
(messages "BIND 9.7.3-P3 crash on multiple cashing servers" and
"bind-9.8.1: INSIST(! dns_rdataset _isassociated(sigrdataset))
failed").
