Here is a reduced testcase with the additional option of --param ggc-min-expand=0 which forces 
collection all the time:
      subroutine foo( nx,j,dble)
      implicit none
      integer i,j,nx
      real*8 x,dble(nx)
      real u(5,60,60)
      do i = 2, nx-1
        x = dble(i) / (nx)
	u(2,i,j) = x
      end do
      return
      end
