This testcase minimized from 173.applu fails in the same place when compiled
with "-m32 -O2 floop-strip-mine -fprefetch-loop-arrays" on powerpc64-linux.

      subroutine blts ( ldmx, ldmy, v, tmp1, i, j, k)
      implicit none
      integer ldmx, ldmy, i, j, k, ip, m, l
      real*8 tmp, tmp1, v( 5, ldmx, ldmy, *), tmat(5,5)

      do ip = 1, 4
        do m = ip+1, 5 
          tmp = tmp1 * tmat( m, ip )
          do l = ip+1, 5
            tmat( m, l ) =  tmat( m, l ) - tmat( ip, l )
          end do
          v( m, i, j, k ) = tmp
        end do
      end do
      return
      end
