query.c:8628: INSIST(qctx->is_zone || (((qctx->client)->query.attributes & 0x20000) != 0)) failed, back trace
Resolver crashes when queried when starting up if both qname minimization and root mirroring is configured.
When we're coming back from recursion we don't accept DNS_R_NXDOMAIN as an answer (hence the INSIST).
Here, the DNS_R_NXDOMAIN is returned by: resume_qmin:4403 -> dns_view_findzonecut:1355 -> dns_db_find()
