This is an issue from Fujitsu testsuite.
Flang-new terminates abnormally when compiling `atomic capture` for complex variable.
The following are the test program and the compilation results of Flang-new and gfortran.
```fortran
! test.f90
module m1
contains
subroutine s1(x,v,e)
complex x,v,e
!$omp atomic capture
v=x
x=-e
!$omp end atomic
end subroutine
end
use m1
complex x,v,e
x=1
v=2
e=3
call s1(x,v,e)
end
```
```console
$ flang-new -v test.f90 -fopenmp
