Comment (by Miguel Zilhão):

i’m trying to fix this in the development version of Lean, but i’m getting very strange warnings. i’ve merely added the following call to the function GetBoundarySizesAndTypes on Boundaries.F90

CCTK_INT  bndsize(6), is_ghostbnd(6), is_symbnd(6), is_physbnd(6)

ierr = GetBoundarySizesAndTypes( cctkGH, 6, bndsize, is_ghostbnd, is_symbnd, is_physbnd )

i don’t use any of the output; i merely call the function. when running a sample parameter file, i’m then showered with a bunch of warnings:
