Follow-up Comment #2, bug #64155 (project groff): I found a solution, it did though need thinking to find it.
test-groff -ww -b -z -fZD /dev/null runs then with no output and returns with zero as exit value. I will leave this bug as is, to give you (plural) a chance to find a solution on your own. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?64155> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
