So i found the problem (which came from me).
The segfault happened because the meyer-heavy.txt had just 10 line (in the
tutorial I didn't read "these are the first 10 lines of meyer-heavy.txt" :(
and I ran event from 0 to 100 steps).
So I just copied ten time these 10 lines and it works.
(I thought 't.getNode(i).createNoiseModel()' create automatically a suite
from the first ten lines...)
