How am I supposed to give you an example? 

gdb nroff? 

I can confirm that -mandoc or -man for that matter on Alpine Linux along
with groff 1.22 shoves the blank page right in the beginning

If in doubt, set up a project, take your time, no one's rushing you,
and install Alpine stable and see for yourself :)

It's interesting

The only version that works without an extra blank page, not extra
really, since it shoves it up in the beginning, is

GNU groff version 1.23.0.rc4.19-96b92 so far

which its compilation finally went through after installing netpbm

But I'm not very keen on the latter, and for a good reason, but heck,
