for instructions.
[to reproduce]
extract tarball and either run `gfortran -freport-bug -c heading_mod.f90
heading_s.f90 classification.f90 classification_s.f90 ` or provided
build_bug.sh script
[further notes]
This code also yields the same error on debian:trixie, so it is not just an
arch package issue. This code does compile with the intel and nag compilers.
