Before we go down a rabbit hole of instrumentation and/or GDB backtracing, I
noticed something there.

These file sizes are the same except for U-TR.  What's going on there?  Is the
U-TR in _/usr/share/groff/1.23.0/font/devpdf/_ a valid font file?  If so, how
does it differ from the one in
_/home/derij/groff-git/groff/build/font/devpdf/_?
