            Bug ID: 63152
           Summary: needless initialization of local pointer arrays.
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Joost.VandeVondele at mat dot ethz.ch

I've noticed that for this code:

 SUBROUTINE S1()
   INTEGER, POINTER, DIMENSION(:) :: v
   INTERFACE
    SUBROUTINE foo(v)
       INTEGER, POINTER, DIMENSION(:) :: v
    END SUBROUTINE
   END INTERFACE
   CALL foo(v)
 END SUBROUTINE S1

gfortran initializes the pointer (to zero) even if '-fno-init-local-zero' :

s1 ()
{
  struct array1_integer(kind=4) v;

  v.data = 0B;
  foo (&v);
}

I don't think this is mandated (other compilers don't)

I'm working on a patch.
