Description V.R.Bom 2006-04-06 11:33:17 CEST

When simulationg 2.45 MeV neutrons on Uranium the following message appears
after a few 100 neutrons:

GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD
Dumping the registered hadronic state information
Nucleus A, Z = 238 92
Projectile was a neutron
projectile momentum (px, py, pz) = (3.55271e-15, 0, 67.89)
Projectile energy = 942.015
GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD_GHAD

I'm running geant4.8.0.p01 with G4NDL3.8, on FC3 with gcc-version 3.4.4

Let's get a little more information:
1) what are all the processes and models assigned to the neutron?
2) is the target a simple block of uranium?
3) is it natural isotopic abundance, or some other mix?

This is now fixed in Geant4 8.1, which is now available.   I reproduced the
segmentation fault in Geant4 8.0 p01, and confirmed that it no longer appears
in Geant4 8.1 (for 10,000 incident neutrons).
