[Gmsh] reading stl and meshing

[Martin Genet]

Dear all:

Attaching a gmsh script + stl that used to work fine (loading the stl, 
remeshing the surface and then meshing the volume), at least until 2.11 
(see test.2.11.0.log), but not anymore (see test-2.13.2.log). I tried 
with 2.12.0, 2.13.0, 2.13.1, 2.13.2, but it just hangs after "Re-orient 
all 0 face normals coherently". Any idea on what might be going on? 
Thanks a lot!

Martin
