# https://github.com/systemd/systemd/pull/12771#issuecomment-502139157 are sorted out at least.
# TODO: "null" should probably be added too. On OSS-Fuzz it was turned off in https://github.com/google/oss-fuzz/pull/674
# TODO: figure out what to do about unsigned-integer-overflow: https://github.com/google/oss-fuzz/issues/910
