The Debian bug I had reported:

Here's the current status. If I remove my glyphtounicode.tex file and
do "apt install --reinstall texlive-base", the problem disappears.

This has the effect to regenerate files in /var/lib/texmf. So now,
correctly appears in /var/lib/texmf/web2c/pdftex/pdflatex.log (while
it previously had /home/vinc17/wd/tex/inputs/glyphtounicode.tex).

If I understand correctly, /var/lib/texmf/web2c/pdftex/pdflatex.fmt is
generated by fmtutil, but its man page does not say that $TEXINPUTS is
used. And I would say that using it would be wrong.
