  Target Milestone: ---

This code snippet ...
   program p
      integer, target :: a(3)
      integer, pointer :: z => a(3)
      z = 0
      print *, z
   end

yields (with gfortran 5.1.1 on SUSE Linux 13.2, 64 bit)

--- Comment #1 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Perhaps it's better to make the target array a bit larger.
And to provide a not so minimalistic version :

   program p
      integer, target :: a(4)
      integer, pointer :: z => a(3)
      call s
   contains
      subroutine s
         a = 123
         z = 0
         print *, a
         print *, z
      end
   end

yields :
f951: internal compiler error: in lhd_set_decl_assembler_name, at
langhooks.c:179

Whereas this modification compiles and works as expected :

$ cat z92.f90
   program p
      integer, target :: a(4)
      integer, pointer :: z
      z => a(3)
      call s
   contains
      subroutine s
         a = 123
         z = 0
         print *, a
         print *, z
      end
   end

$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z92.f90
$ a.out
         123         123           0         123
           0

Confirmed from 4.8 up to trunk (6.0). Note that the error for trunk configured
with the default value of --enable-checking is
