Description michel.maire 2013-01-18 18:41:59 CET 
While using neutronHP, one get a segmentation fault in G4HadronicProcessStore::GetCrossSectionPerAtom()
Comment 1 dennis.herbert.wright 2013-01-28 18:01:03 CET 
Is this problem in version 9.6?

Hi 

I think this is not a proble in HP.
The problem is happend in 

G4double GetElasticCrossSectionPerAtom(
     const G4ParticleDefinition *aParticle,
     G4double kineticEnergy,
     const G4Element *anElement, 
const G4Material* mat=0);


ComputeCrossSectionPerVolume()

Hi 

I think this is not a problem in HP.
The problem is happened in 

G4double GetElasticCrossSectionPerAtom(
     const G4ParticleDefinition *aParticle,
     G4double kineticEnergy,
     const G4Element *anElement, 
     const G4Material* mat=0);

The last argument has default NULL value and this caused trouble in later phase
especially in HP.
This is not allowed in ComputeCrossSectionPerVolume() and this is the reason
this method works correctly as Michel wrote.

Hi Michel,

   Is this problem still happening?  Have you tried it with a recent tag?
