<pre>
    When building FDS(https://github.com/firemodels/fds), Flang-new resulted in compilation error such as:

```console
error: loc("/tmp/fds/Build/ompi_gnu_linux/../../Source/divg.f90":818:24): 'fir.allocmem' op invalid type for allocation
error: verification of lowering to FIR failed
make: *** [../makefile:121: divg.o] Error 1
make: *** Waiting for unfinished jobs....
```

The compilation error occurred in https://github.com/firemodels/fds/blob/f190e405e03d7f7e04af64038898fa3cf21e4897/Source/divg.f90#L818.

This problem is probably the same as https://github.com/llvm/llvm-project/issues/81946, but I think it's important to report based on a specific application, so I've written this. Note that I reused the route for the GNU compiler in the existing makefile with some options removed.
