Problem 257

I am trying to simulate some neutron transport benchmark experiment. So I found
that Test11 had a physics list which seemed to implement a lot of processes for
neutrons. I have incorporated and modified slightly (to make it easier to
configure) into my code. After 165 events I get a crash with the folloing stack:

============

I have put the code in /afs/cern.ch/user/i/iglez2/public/Neutrons/Tiara.tar.gz.
If you want to test it, copy to your pref. dir and...
% gunzip Tiara.tar.gz
% tar xvf Tiara.tar
% source configure.csh (modify the variables, like G4INSTALL or LHXX_BASE,
inside)
% gmake
% Tiara
....
Idle> run/beamOn 165

And wait (the program requires 180 Mb of memory to run because of Neutron HP
processes).
