Sorry for the late reply on this, but I only now got a chance to (try to)
update manpages.debian.org to mandoc-1.14.5.

Unfortunately, I encounter an assertion failure when running:
% curl -s
https://manpages.debian.org/testing/libpcp3-dev/pmRegisterDerived.3.en.gz |
mandoc -Thtml
[…]
mandoc: html.c:809: print_text: Assertion `NULL == h->metaf' failed.
