[Dune] parallelamgtest

[Bernd Flemisch]

Dear Dune,

I am trying to run parallelamgtest in istl/paamg/test. In order to 
really test the AMG, I uncommented lines 153-176, commented lines 
178-188, and changed the construction of amg in line 153 to
AMG amg(fop, criterion, smootherArgs, 1, 2, 2, false, comm);
I also attached the file.

Even running sequentially, I get a segmentation fault, see below. 
Running in parallel does not make it better. I run into the same problem 
in dune-dd/nonoverlappingclassic if I try to include the AMG.

Can you help me to get it to run?

Thank you very much. All the best
Bernd
