    I am building on macOS with a MacPorts-provided flang-new:
```
$ flang-new-mp-18 --version
flang-new version 18.1.1
Target: x86_64-apple-darwin23.4.0
Thread model: posix
InstalledDir: /opt/local/libexec/llvm-18/bin
```

I see this error:
```
$ flang-new-mp-18 -c hello-world-fortran08.f90
error: loc("/tmp/f/hello-world-fortran08.f90":4:3): /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_llvm-18/flang-18/work/llvm-project-18.1.1.src/flang/lib/Lower/ConvertExprToHLFIR.cpp:309: not yet implemented: lowering symbol to HLFIR
LLVM ERROR: aborting
```

The same code works with LLVM version 17.

The source code is spread over several source files (several modules and one main program). I tried to reduce the number of modules but this made the error go away. I am thus submitting several files. I did reduce the test case to 71 lines overall. I am also including a script `build.sh` that builds the modules in a correct order.

(The instructions for reporting an LLVM bug don't quite work because they assume I'm using the C/C++ compiler clang, and flang-new doesn't accept the same command line options.)
