I would agree with your comments.

With move_alloc, gfortran-4.5 rejects only (1), gfortran-4.6 rejects all of
them.

It does. In that sense I agree that the patch is not completely correct.

There 'tx' here should be an 'x', I guess.


>   call move_alloc (x%a, a)      ! Invalid (2)

This one corresponds to the original test case.
