I have discovered that some long character domain names in RPZ file is causing Unbound to crash.
Apr 23 18:35:55 unbound: [21240:0] error: parse error /zones/rpz.oisd.zone 1602:256: Domainname length overflow
Apr 23 18:35:55 unbound: [21240:0] error: error parsing zonefile /zones/rpz.oisd.zone for rpz.oisd.zone.
Apr 23 18:35:55 unbound: [21240:0] fatal error: auth_zones could not be setup
Apr 23 18:36:07 unbound: [21278:0] error: parse error /zones/rpz.oisd.zone 1602:256: Domainname length overflow

Domain example;
11exe.yourcomputerhaveaseriousproblemcallon18662968997exe.yourcomputerhaveaseriousproblemcallon18662968997exe.yourcomputerhaveaseriousproblemcallon18662968997exe.yourcomputerhaveaseriousproblemcallon18662968997calltollfreenow.playnewgamesonline.com CNAME .
If you perform DIG on this domain it is valid and comes back NOERROR
