This is an issue from Fujitsu testsuite.
Flang-new terminates abnormally when compiling `declare reduction` directive.
(Probably it has not been implemented yet.)
The following are the test program, Flang-new and gfortran compilation result.
```fortran
! test.f90
!$omp declare reduction(ior:real(4):omp_out=omp_in+omp_out)
end
```
```console
$ flang-new -v test.f90 -fopenmp
flang-new version 18.0.0 (https://github.com/llvm/llvm-project.git 444abb396c340e52a8a4db5778b7d6b3b6195070)
