I wanted to update DoFTools::make_hanging_node_constraints is not the issue
above. Even I comment out that line and call ConstraintMatrix.close() prior to
calling make_periodicity_constraints, I still get the same error. This means
calling ConstraintMatrix.close() on a constraintMatrix with no constraints is
leading to the error.
That should be easy to test. Can you create a minimal working example that
demonstrates this and that we can turn into a testcase after the bug is fixed?
You've got a good start with your program, but keep removing things that are
not necessary while making sure that the bug still appears. *Everything*
that's not necessary should go to expose the problem as clearly as possible!
