Regression on character function

[Rouson, Damian]

Gfortran developers,

A build from a snapshot of the development branch as of two days ago
(installed by macports) appears to have a regression on deferred-length
character functions.  The text below shows a test that compiles with gcc
4.6.2 but not with 4.7.  Should I file a PR?

$ cat character_function.F90
module foo_class 
  implicit none 
  type foo 
  contains 
    procedure :: bar
  end type 
contains 
  function bar(this)
    class(foo) :: this
    character(:), allocatable :: bar
  end function 
end module 
$ /opt/local/bin/gfortran-mp-4.6 -c character_function.F90
$ /opt/local/bin/gfortran-mp-4.7 -c character_function.F90
character_function.F90:9.22:

    class(foo) :: this
                      1
Error: Deferred-length character component 'bar' at (1) is not yet
supported
