Fortunately, that is enough to track down what is issuing the diagnostic.
https://git.savannah.gnu.org/cgit/groff.git/tree/src/preproc/html/pre-html.cpp?h=1.23.0#n1136
I can see some ways to improve diagnostics in this file, even if in the long
run I want to kill off `pre-grohtml` entirely.
But in the meantime, if you got this error simply by running groff's own make
targets, that suggests some kind of race.
However, it would be hasty to assume that this problem exists in stock groff
1.23.0 as we see evidence that you're not using that.
MFLAG = -M$(abs_top_builddir)/s-tmac
Stripped tmac files are not a feature of groff 1.23.0.
If you can't reproduce this with stock groff 1.23.0, I think we'll need to
resolve it as invalid.
