--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-12-02 16:21:50 UTC ---
At least for the following test case there is a regression. While the "must be
ALLOCATABLE" is printed correctly three times with GCC 4.6, with GCC 4.7 I only
get the error for ASSOCIATE (as expected, cf. comment 2) and not for SELECT
TYPE.

type t
end type t
class(t), allocatable :: x

! Expected: An error, but none is printed:
select type(x)
  type is(t)
    print *, allocated (x) ! { dg-error "must be ALLOCATABLE" }
end select

! Expected: An error, but none is printed:
select type(y=>x)
  type is(t)
    print *, allocated (y)  ! { dg-error "must be ALLOCATABLE" }
end select

! Here, the error is printed:
associate (y=>x)
  print *, allocated (y)  ! { dg-error "must be ALLOCATABLE" }
end associate
end
