Version of flang-new : 19.0.0(1a498103ee5c4d101e70dc49db11938d8b87b518)/AArch64
```
When the variables (`x` and `expr`) used in an `update-statement` in `atomic` construct are declared with different types, a compilation terminates abnormally.
When both variables are declared of the same type, a compilation terminates normally.
The following are the test program, Flang-new, Gfortran and ifort compilation/execution result.
OMP_3_O_007_4_atm_expr_027_up_323.f90:
```fortran
program main
integer(kind=4) :: s_x, i
! integer(kind=4) :: s_expr
real(kind=4) :: s_expr
s_x = 3
s_expr = 3.0
!$omp atomic ! update
s_x = s_x + s_expr
!$omp end atomic
write(6,*) 's_x = ', s_x, ', s_expr = ', s_expr
end program main
```
```
