The code below is invalid, but it's not that
bad that a segfault is called for :-)

$ cat sel_int_kind.f90
program foo
contains
  subroutine foo(i)
    integer :: i
    character(len=selected_int_kind(i)) :: c
  end subroutine bar
end program foo
$ gfortran sel_int_kind.f90
 In file sel_int_kind.f90:3

  subroutine foo(i)
               1
Error: PROGRAM attribute conflicts with PROCEDURE attribute at (1)
 In file sel_int_kind.f90:4

    integer :: i
