[Dune] Assertion when reading an ALUGrid<3,3> from gmsh

[Jö Fahlke]

Hi!

I'm trying to read in a .msh file into an ALUSimplexGrid<3,3> using Dune's
GmshReader.

If get the following error (full error is given below):

| lt-fetd-3D: serial/gitter_mgb.cc:835: void ALUGridSpace::MacroGridBuilder::finalize(): Assertion `((hface3_GEO *)(*int).second)->ref == 2' failed.

The error message means nothing to me.  Does this ring a bell with anyone?  If
not, don't think too hard about it, gmsh seems to have problems with this file
as well and often segfaults when working with it.

Thanks,
Jö.

Full error message, has been run through "c++filt -t":
