[RFC]: Add test for verifying the fix to the SEGV error when printingF77 array element


Daniel and all,

This is the testcase associated with the following patch:

   http://sources.redhat.com/ml/gdb-patches/2005-06/msg00090.html	

Without the patch above, the last three tests fail. With the patch, all
tests pass.  It is tested on ppc64 with g77-3.3.3 and g77-3.4.3.

It is my first attempt to add a new testcase into GDB testsuite. So if 
there is any errors or missings, please feel free to tell me. Thanks a 
lot!

array_element.f
======================================
        dimension a(10)
        write(*,*)'This is a test.'
        call sub(a,10)
        write(*,*) a
        stop
        end

        subroutine sub(a,n)
        dimension a(n)
        do 100 i=1, n 
          a(i)=i
100     continue
        return
        end
