I did not check carefully enough. Using two processes, it still crashes, 
but this time at least with an assertion:

parallelamgtest: ../../../dune/istl/paamg/galerkin.hh:587: M* 
Dune::Amg::GalerkinProduct<T>::build(const M&, G&, V&, const T&, const 
Dune::Amg::AggregatesMap<typename G::VertexDescriptor>&, const typename 
M::size_type&, const Set&) [with M = 
Dune::BCRSMatrix<Dune::FieldMatrix<double, 1, 1>, Dune::ISTLAllocator>, 
G = Dune::Amg::MatrixGraph<const 
Dune::BCRSMatrix<Dune::FieldMatrix<double, 1, 1>, Dune::ISTLAllocator> 
 >, V = Dune::IteratorPropertyMap<std::_Bit_iterator, Dune::IdentityMap, 
bool, std::_Bit_reference>, Set = 
Dune::EnumItem<Dune::OwnerOverlapCopyAttributeSet::AttributeSet, 0>, T = 
Dune::OwnerOverlapCopyCommunication<int, int>]: Assertion 
`aggregates[*vertex] != AggregatesMap<typename 
G::VertexDescriptor>::UNAGGREGATED' failed.

Unfortunately, I cannot reopen the bug report:
(ERROR: null value in column "deny_reason" violates not-null constraint)

Best wishes
Bernd
