[Flang][OpenMP] Compilation error when lastprivate clause specified in do construct has a derived type with an allocatable variable

[ohno-fj]

Version of flang-new : 19.0.0(1a498103ee5c4d101e70dc49db11938d8b87b518)/AArch64

When lastprivate clause specified in do construct has a derived type with an allocatable variable, a compilation terminates abnormally.
When lastprivate clause in do construct is removed, a compilation terminates normally.

The following are the test program, Flang-new, Gfortran and ifort compilation/execution result.

lp10_32.f90:

subroutine s4
  type y3
     integer,allocatable::x
  end type y3
  type(y3)::v
  allocate(v%x)
  v%x=0
!$omp parallel
  if (.not. allocated(v%x)) print *,'101'
!$omp do lastprivate(v)
  do i=1,10
     v%x=i
  end do
!$omp end do
!$omp end parallel
end subroutine s4

program main
  call s4
  print *,'pass'
end program main

$ export OMP_NUM_THREADS=2; flang-new -fopenmp lp10_32.f90; ./a.out

Thank you for reporting this. It should be fixed by #100417
