I am preparing the next relase of doxygen (1.8.15).
Last week it built fine with texlive-base 2018.20181214-1.
I tried today with 2018.20190126-1 and it fails.
You can see the trace of the successful build here:
https://salsa.debian.org/paolog-guest/doxygen/-/jobs/107680
and of the failed build here:
https://salsa.debian.org/paolog-guest/doxygen/-/jobs/115667
I attach the files necessary to reproduce (I took the files in
doxygen/debian/build at the end of the failed build and blanked a few to reduce
the size of the attachment).
