Looks great to me. Nice work.

Regarding this case:
```
allocate(ptr(10))
!$acc parallel private(ptr)...
deallocate(ptr)
```

So when pointer variable privatization was made, the decision was to actually allocate a private copy when the pointer was associated. This was not spec specified behavior - and another reasonable behavior would be to only create an unassociated copy. Anyway, the pattern you described wouldn't work with that approach either - and the error message is reasonable behavior that I am comfortable with.
