[Bug fortran/30655] New: Undue out-of-bounds warning

[fxcoudert at gcc dot gnu dot org]

gfortran should not report an out-of-bounds access on the following code:

$ cat a.f90
  integer i(12), j
  j = -1
  i(0:j) = 42
  end
$ gfortran a.f90                       
a.f90:3.4:

  i(0:j) = 42
   1
Warning: Array reference at (1) is out of bounds


Compiling with -fbounds-check and running it doesn't error, which means the
-fbounds-check code is generated fine. But, somewhere, the front-end is
over-zealous (it doesn't know about stride). I thought I had that fixed at some
point...
