Dear Dune,

I have been attempting to debug this particular problem for over a week now, but to no avail. I have a suspicion that the bug is inside the checkCommunication.cc class.

I run the following test on a single (!) core

- -----------------------------------------------------------------------------------------------

static Dune::MPIHelper & mpihelper = Dune::MPIHelper::instance(argc, argv);
typedef Dune::CurvilinearGrid<3, 3, double, isGeometryCached> GridType;
GridType * grid = CurvFactory<double, 3, 1>::buildGrid(mpihelper);

std::cout << "-- Running Base GridCheck" << std::endl;
gridcheck(grid);

std::cout << "-- Checking LeafGridView" << std::endl;
checkIterators ( grid.leafGridView() );

std::cout << "-- Checking LevelGridView" << std::endl;
checkIterators ( grid.levelGridView(0) );

std::cout << "-- Checking Communication" << std::endl;
//checkCommunication(grid, -1, Dune::dvverb);
//for(int l=0; l<=grid.maxLevel(); ++l)  { checkCommunication(grid,l,Dune::dvverb); }

std::cout << "-- Checking Geometry Lifetime" << std::endl;
checkGeometryLifetime( grid.leafGridView() );

std::cout << "-- Checking Geometry in Father" << std::endl;
checkGeometryInFather(grid);

std::cout << "-- Checking Intersection Iterator" << std::endl;
checkIntersectionIterator(grid);

std::cout << "-- Checking Adaptive Refinement" << std::endl;
checkAdaptRefinement(grid);

std::cout << "-- Checking Partition Type of LeafGridView" << std::endl;
checkPartitionType( grid.leafGridView() );

- ------------------------------------------------------------------------------------------------

This test runs without crashes. Now, if I uncomment the checkCommunication and comment all other tests, I get a segmentation fault.

Please find the Valgrind output for the crash below. Any advice on this bug would be appreciated

Regards,
Aleksejs

valgrind: Heap block lo/hi size mismatch: lo = 80, hi = 4606463542527295847.
This is probably caused by your program erroneously writing past the
end of a heap block and corrupting heap metadata.  If you fix any
invalid writes reported by Memcheck, this assertion failure will
probably go away.  Please try that before reporting this as a bug.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.
