["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following error should not happen:

$ cat substr_3.f 
      implicit none
      character(len=10) :: s, t
      integer :: i, j

      s = "abcdefghij"
      t(:10) = s(1:)
      s(16:15) = "foo"
      if (s /= t) call abort
      end
$ gfortran substr_3.f
 In file substr_3.f:9

      s(16:15) = "foo"
