Hi Juhana and maintainers, I can confirm that this (or similar) bug manifests itself on i386/amd64 platforms in the dnssec-signzone tool. It happens only from time to time, sometimes it happens everytime and you have to rerun signing command several times and sometime it doesn't happen at all. Error message is:
$ /usr/sbin/dnssec-signzone -g -d . -o obscure.cz. -e +1209600 -N unixtime zone.db K*.private task.c:311: REQUIRE(task->references > 0) failed. Aborted And arch is amd64.
