Okay.  I see I missed the

  if (p.data != 0)
    {
      {
        real4[0:] * * ptr.1;
        ptr.1 = &p.data;
        _gfortran_deallocate (ptr.1, 0);
      }

because I was looking for a D.xyz variable.  I don't know the 
tree stuff very well.  Is it sufficient to use 

     tmp = build2 (NE_EXPR, boolean_type_node, tmp, 
          convert (TREE_TYPE (tmp), integer_zero_node));
