Here is the reduced fortran testcase (I tried to convert it to C but I must not be matching all the syntax 
correctly) and change the names so I would not get into trouble with SPEC:
      subroutine function11(max)
      parameter(maxindex=64)
      common array1(maxindex),array2(maxindex)
      save
      do 20 j=1,max
	array1(j)=array2(j)
   20   continue
      return
      end
