Question Problem in Ion definition 

Forum: Particles
Date: 20 Jan, 2009
From: Adrien MATTA <Adrien MATTA>

Hello Everyone,

I'm facing new problem since I use my code on the new Geant4 release (and a different computer). When I'm calling the GetIon(Z,A,E) method a segmentation violation occured. The debugging message let think the problem occured when the above method called the G4LossTableBuilder::BuildDEDXTable NB:The GetIon method is called after Initialisation of G4 kernel. I don't have the warning message about creating Ion in preInit state.

Here part of my code: (physics list)

NB: the first 'TEST' print occured, then I have my segmentation violation

///////////// Construction of unstable Nuclei and Decay Channel ////////////////////

	G4ParticleTable* particleTable = G4ParticleTable::GetParticleTable();
	G4ParticleDefinition* particle;
	G4VDecayChannel* channel;
  	G4double flat[1];flat[0]=1;
CLHEP::RandGeneral* randflat = new CLHEP::RandGeneral(flat,1);

 G4DecayTable* table10He  = new G4DecayTable();
 G4cout << " TEST " << G4endl;
 particle = particleTable->GetIon(2,10,1.);
 G4cout << " TEST " << G4endl;
//Setting a 2 neutron Decay channel using the 3 product decay
channel = new  G4NuclearDecayChannel (	
IT, 			// mode
0,			// verbose
particle,		// parent nucleus
1.,			// BR 
0.,			// FFN 
false,randflat,	        // betaSimple,randBeta
-2.068*MeV,		// Q
8, 			// A
2,			// Z
0.,			// Daughter Excitation
"neutron",		// Daughter2
"neutron");		// Daughter3

table10He->Insert(channel); particle->SetDecayTable(table10He);


And here part of the error message:

The program is running.  Quit anyway (and detach it)? (y or n) [answered Y; input not from terminal]
Detaching from program: /proc/4975/exe, process 4975


I tried using static library only, and it did the same. I also search the forum for answer but didn't manage to find something...

Did I miss something? Thanks in advance.
