Please see the problems shown on
https://cran.r-project.org/web/checks/check_results_image.dlib.html.

Specifically, please see the clang19 additional issues.

These show compilation problems using the compilers from LLVM 19,
finally released yesterday. The results are for Fedora 36 (see
https://www.stats.ox.ac.uk/pub/bdr/clang19/README.txt) and can
conveniently be reproduced using the clang-19 and flang-19 packages in
Debian unstable.
