-// we get this crash:
-//
-// An error occurred in line <4677> of file </scratch/deal-trunk/deal.II/include/deal.II/numerics/vectors.templates.h> in function
-// void dealii::VectorTools::compute_no_normal_flux_constraints(const DH<dim, spacedim>&, unsigned int, const std::set<unsigned char>&, dealii::ConstraintMatrix&, const dealii::Mapping<dim, spacedim>&) [with int dim = 2, DH = dealii::DoFHandler, int spacedim = 2]
-// The violated condition was:
-// std::fabs(determinant (t)) > 1e-3
-// The name and call sequence of the exception was:
-// ExcMessage("Found a set of normal vectors that are nearly collinear.")
-// Additional Information:
-// Found a set of normal vectors that are nearly collinear.
-
-// the crash does not happen without a boundary object. Same error occures with HyperShellBoundary instead of HalfHyperShellBoundary.
