Yes, on running 'gmsh -2 Dominio.geo', I see this too:
Warning : Could not orient normal of surface 1
I'm not immediately sure why though... I continue to suspect that this warning
is associated with the error from FreeFEM about triangular elements having
negative areas, but I haven't been able to work out what the problem with
Dominio.brep is, i.e. why Gmsh can't orient the Plane Surface.
I even get the same warning from Gmsh when trying to make a simple Plane
Surface from either of the two Curve Loops separately. That does seem odd to
me since the second, which looks like an island (or is it a lake) is simple
enough to be inspected manually in the Gmsh GUI and it looks fine.
Sorry, I'm not sure what to suggest from here..._______________________________________________
