The missing map (from: r) is obvious.  Explicitly mentioned f and j is
tested in another part of the test, here I believe it should be implicitly
firstprivate, and then
"If the original list item has the POINTER attribute, the new list items
receive the same association status of the original list item as if by
pointer assignment."
shall apply.  I think I'd prefer the test to be broken over forgetting this
isn't handled correctly.
