The problem here is that we are passing a private variable to a routine that expects a global variable. I don't think that the code to smooth the depth of the bottom boundary layer, hbbl, is correct here. We need to smooth hbbl and not the thickness hbbl(:,:)-z_w(:,:,0), as we do for the hsbl: 

      CALL shapiro2d_tile (ng, tile, iNLM,                              &
     &                     LBi, UBi, LBj, UBj,                          &
#  ifdef MASKING
     &                     rmask,                                       &
#  endif
     &                     hbbl)

We need to be consistent with lateral boundary conditions, parallelism, and exchanges. Anyway, the smoothing (order=2) here is a linear operator. Thank you for reporting this problem.
