Thank you, makes sense. In that case the problem occurs at OMP lowering:
  voidD.27 copyin_simple (struct simple & restrict varD.3961)
  {
    var.0_1 = varD.3961;
    {
      D.3965.D.3963 = var.0_1;
      D.3965.varD.3964 = &varD.3961;
      #pragma omp target oacc_enter_exit_data map(to:*var.0_1 [len: 8])
map(alloc:varD.3961 [pointer assign, bias: 0])
