[Bug 1085593] [NEW] bind 9.8.1-P1 crashes with an assertion failure

[Alexander Gurvitz]

Public bug reported:

Ubuntu 12.04.1 LTS
1:9.8.1.dfsg.P1-4ubuntu0.4

While loading a certain zone file (attached) and using auto-dnssec (see
the conf below), bind crashes with an "assertion failure" message. This
bug seems to be fixed in the latest ISC releases - 9.8.4 and 9.9.2,
please backport the patch.

(The attached zone file is not exactly correct, but should not result in
an assertion failure).

named.conf:
zone net-me.net {
    type master;
    file "db";
    allow-update {127.0.0.1;};
    auto-dnssec allow;
};

Error log:
