Details:

"hackerb9" reported a problem to the groff mailing list.

https://lists.gnu.org/archive/html/groff/2020-09/msg00046.html

At first it was difficult to reproduce but things became clear when the -P
argument was removed and standard output closed instead.

To reproduce:


echo foo | groff >&-


I have a fix in preparation.
