<pre>
    This is an issue from Fujitsu testsuite.

Flang-new terminates abnormally when compiling `ordered` clause not in DO loops.

The following are the test program, Flang-new and gfortran compilation result.

```fortran
! test.f90
subroutine sub()
implicit none
integer::i
integer::k=0
!$omp ordered 
do i=1,1
k=k+1
enddo
!$omp end ordered
end
```
```console
