[Dune] Error if first action is iterating over ghost nodes with ALU

[Patrick Leidenberger]

Hi all,

I stumbled over a strange behavior of the iterator over ghost nodes with 
ALU simplices in 3d:
If the first action in my code (after grid creation) is an iteration 
over the ghost nodes the execution of the parallel code stops with the 
message shown below this mail.

If I do some other iterator before the ghost iteration, everything is 
fine. (set 'true' in line 90)

I attached the modified test-alugrid from dune-grid/dune/grid/test/ to 
demonstrate the bug.

My system has not changed since my last mail:
Current dune from SVN, last co 26h ago.
dune-grid rev 7698
ALUgrid 1.23, with simplices in 3d
Standart Ubuntu 11.04, 10.10 with standart gcc, openmpi & co.

Is this behavior normal or a bug?

Best regards

Patrick
