Close, but not quite :)

It's actually r150047, as I just found out. However, this revision only
introduces the first ICE in the test case:

module m_string

  procedure(string_to_char) :: char1                    ! ICE #1

!   procedure(string_to_char),pointer :: char2          ! ICE #2

!   type t_string
!     procedure(string_to_char),pointer,nopass :: char3 ! ICE #3
!   end type t_string

contains

  function string_to_char (s) result(res)
    character, dimension(:), intent(in) :: s
    character(len=size(s)) :: res
  end function string_to_char

end module m_string


The second one is already there at r150046. For this I found a window of
147438:148816 up to now. Will try to find out more.


The third ICE is not present at 150047, but is apparently masked by another
error:

    character(len=size(s)) :: res
                  1
Error: Character length of component 'char3' needs to be a constant
specification expression at (1)
