Description
Version of flang-new : 19.0.0(8930ba98e01bc66949e482b396f8389d64388359)/AArch64
When capture-statement described in atomic read construct contains a different type, the compilation terminates abnormally.
Compilation ends normally in the following cases:
- Do not specify the compilation option (
-fopenmp)
The following are the test program, Flang-new, Gfortran and ifort compilation/execution result.
OMP_3_O_007_4_atm_type_006_re_22.f90:
subroutine sub2()
real(kind=4) :: s_v_r2
complex(kind=4) :: s_x_c2
s_v_r2 = 0.0
s_x_c2 = (1.0,2.0)
!$omp atomic read
s_v_r2 = s_x_c2
!$omp end atomic
write(6,*) "s_v_r2 = ", s_v_r2
end subroutine sub2
program main
call sub2()
end program$ flang-new -fopenmp OMP_3_O_007_4_atm_type_006_re_22.f90
