Workaround for gfortran 4.9.2 regression

[kilian]

There is code in syntax_rules.f90 that causes an ICE in gfortran 4.9.2, but not in earlier versions. Here is a reduction:

module string_pairs

  type :: string_t
     character, dimension(:), allocatable :: chars
  end type string_t

  type :: string_pair_t
     type(string_t), dimension(2) :: pair
  end type string_pair_t

contains

  subroutine proc (arg)
    class(string_pair_t), intent(in) :: arg
  end subroutine proc

end module string_pairs

If there's no compiler fix, I'll do a workaround (simply eliminate the dimension(2) string array).

[Juergen Reuter]

I will post this on bugzilla, but please do a workaround as gfortran 4.9.3 is not yet out and people might use this specific compiler.
