The (more or less) minimal code example to produce this (on my machine) is:

#ifdef HAVE_CONFIG_H
# include "config.h"     
#endif

#include <iostream>

#include <dune/istl/bcrsmatrix.hh>
#include <dune/istl/matrixindexset.hh>
#include <dune/istl/bvector.hh>
#include <dune/istl/solvers.hh>
#include <dune/istl/superlu.hh>

using namespace Dune;

int main (int argc, char *argv[]) try
{

	typedef Dune::BCRSMatrix< Dune::FieldMatrix<double,1,1> > Matrix;
	typedef Dune::BlockVector< Dune::FieldVector<double,1> > Vector;

	const int N=9;

	Matrix A;
	MatrixIndexSet indices(9,9);

	for (int i=0; i<N; ++i) {
		for (int j=0; j<N; ++j) {
			if ((j<N/4+i and i<N/4+j) or (j==N/2+i or i==N/2+j) or (j==N-2+i or i==N-2+j)) {
				indices.add(i,j);
				std::cout << "
