Subject: [Bug fortran/23677] New: -fno-automatic does not accept legal save statements

List-Id: <gcc-bugs.sourceware.org>

The following code fails

[/Users/fca] more test.f
      subroutine test(bbb)
      implicit double precision (A-H,O-Z)
      double precision blob(100),bbb(100)
      data blob /100*-1/
      save blob
      do j=1,100
        blob(j)=bbb(j)
      enddo
      end
[/Users/fca] /opt/gcc-4_0/bin/gfortran -c -fno-automatic test.f
 In file test.f:3

      double precision blob(100),bbb(100)                               
                               1
Error: Duplicate SAVE attribute specified at (1)

Two remarks. 

- Non-contraddictory declarations should not cause compilation to fail (see with double precision)

- A compiler switch should not turn valid code into non-compilable code
