This is an issue from Fujitsu testsuite.
Flang-new doesn't emit a correct error message for a wrong usage of `atomic capture`.
The following are the test program and the compilation results of Flang-new and gfortran.
```fortran
! test.f90
integer :: vv,yy,yy1
vv=1
yy=1
yy1=1
!$omp atomic capture
vv=yy
yy=yy+yy
!$omp end atomic
!$omp atomic capture
vv=yy
yy=(yy1+yy)+yy1
!$omp end atomic
end
```
```console
$ flang-new -v test.f90 -fopenmp
