Description
Version of flang-new : 19.0.0(dd7386d85f11cf6ad911b9827c7018fb08c6c205)/AArch64
If type complex is used with expression-stmt in atomic construct, the compilation terminates abnormally.
If type complex is changed to type real or integer, the compilation terminates normally.
The following are the test program, Flang-new, Gfortran and ifort compilation result.
omp_PARALLEL_001c_21.f90:
program main
complex(kind=8)::ca
ca = (0.0,0.0)
!$omp parallel
!$omp atomic
ca = ca + (1.0,0.0)
!$omp end parallel
write(6,*) "pass"
end$ flang-new -fopenmp omp_PARALLEL_001c_21.f90
error: loc("/work/home/ohno/CT/test/fort/tp/reproducerJ/fomp_complex/omp_PARALLEL_001c_21.f90":3:7): no atomic update operation with region argument as operand found inside atomic.update region
