Hi Gnulib mavens,

I happened upon a baffling bug today.

https://savannah.gnu.org/bugs/?68552

Long story short is the question in the Subject:.

If Gnulib doesn't--I checked its module list[1] and grepped the lib/
directory housing Gnulib functions in an affected build and saw no
evidence that it does--then I may have to risk the exciting political
gambit of throwing shade on a compiler vendor or a distribution.

The good news is that this seems _not_ to be a release blocker for
groff.  If the problem ain't in groff, I can't fix it in groff.

Regards,
Branden
