That is really strange. I ran the stuff on some other
machines (smaller ones, like yours) and I can't see this problem
also. So I think it is not a problem of the binary, but something
with the machine, which is also strange because
all other applications we have run without any problems
there. (e.g. matlab with the same commands)

It is just no oviously what is wrong.
Wihtin matlab I allocated tons of memory (14GB) just to see
if it is a problem of the machine, but it didn't appear like this.
I just have no idea what's going on.
