            Bug ID: 59395
           Summary: internal compiler error (memory access error)
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: demarchie at web dot de

I receive an ICE when compiling this source code with 4.8.1 and 4.8.2:

module mymod
  implicit none

  integer, parameter :: k = selected_real_kind(1,1) ! no bug with k = 4

  type t
   integer                       :: m   ! can't swap this line with next one
   procedure(f), pointer, nopass :: a,b ! have to be at least two of them
  end type

  interface
    integer function f(n)
      integer :: n
    end function
  end interface

end module mymod

program test
  use mymod
end program test
