The example from bug 45170 comment 41 fails with an ICE on Fortran-Dev
  internal compiler error: in record_reference, at cgraphbuild.c:66

It works with GCC 4.8/4.9


module thing
    implicit none
    character(len=:), allocatable :: array_of_chars(:)
    contains

      subroutine allocatestuff()
        implicit none
        integer :: length_names = 15
        integer :: number_arrays  = 5

        allocate(character(15) :: array_of_chars(number_arrays))
        !allocate(character(length_names) :: array_of_chars(number_arrays))

      end subroutine allocatestuff

end module thing

program test1
implicit none


      call allocatestuff()

end program test1
