[Juha Ruokolainen <jpr at csc dot fi>]

Hi,

latest linux/i386 gfortran binary from wiki ices compiling the code below

!---------------------------
module mod
  implicit none
  type a_t
     type(a_t), pointer :: n
  end type a_t
end module mod

subroutine a
contains
  subroutine b()
    use mod
    type(a_t) :: v
  end subroutine b
end subroutine a
!-----------------------------

If i move the "use mod" from the contained subroutine up to
containing subroutine it seems to work. Is this a known bug?
