[Dune] UG grid problem: ID overflow DDD_HdrConstructor

[Eike Mueller]

Dear dune-list,

I'm having trouble with using the parallel DUNE grid, and I keep getting the

DDD [000] FATAL 02221: global ID overflow DDD_HdrConstructor

error. My grid is not very large, I use 6*2^5 = 6144 elements on 6 processors. I had a look at Flyspray Task #250 [1], and 
followed the instructions there, in particular I set -DDDD_GID_T=long and use 20 bits for the processor part 
(--with-ddd-maxprocbits=20). I recompiled both UG and Dune (version 2.2) with these flags, and also recompiled my own code with 
them. I checked that long is really 8 bytes (=64 byte) on the machine I'm using, but I still get the error.
I generate the grid using the UG grid factory by reading from a .dgf file with the attached classes.
If I make the grid smaller, the problem eventually disappears but I get a segmentation fault.
I should also say that on a different machine, where I did not change the maxprocbit and GID_T, it all works fine for small grids.

Is there anything I might have overlooked? For example, do I have to be careful with the datatypes I use when constructing the 
grid with the factory?

Thanks a lot,

Eike
