I can't reproduce the problem that way, either. I'm using Ubuntu 21.04. 
I clone Savannah's latest groff 
(7ae6d67b7c310c54bb7176c761b1f9719e64201a), run this:

./bootstrap --gnulib-srcdir=$HOME/src/gnu/gnulib-savannah
./configure
make CFLAGS='-ggdb -Og'

and it builds (there are quite a few warnings, which should get fixed, 
but nothing fatal to the build). $HOME/src/gnu/gnulib-savannah contains 
a copy of Savannah's latest Gnulib (commit 
804ac808a9b17d7ee7cf49f7c713c4a4e4d6423f).

The symptoms you're reporting are that of a partial build that isn't 
being resumed correctly somehow.

By the way, I've not had much luck with -Og. I have better luck with -O0 
when debugging. But then, I mostly debug C code, not C++.
