In my sim, I issue many particleGun->GeneratePrimaryVertex(anEvent) commands per event. In one event I had to issue over 200.000 such commands at the same event.

After the event is processed and the destructors are being called I receive segmentation fault from G4PrimaryVertex::~G4PrimaryVertex.

I went to the source code of G4PrimaryVertex.cc and changed to the code to

G4PrimaryVertex::~G4PrimaryVertex()
{
G4cout <<"1";
  if(theParticle != 0) { G4cout <<"2"; delete theParticle; G4cout <<"3";}
G4cout <<"4";
  if(nextVertex != 0)  { G4cout <<"5"; delete nextVertex;G4cout <<"6"; }
G4cout <<"7";
  if(userInfo != 0)  {G4cout <<"8"; delete userInfo; G4cout <<"9";}
G4cout <<"10"<<G4endl;
}


For a good event I get
Event #29697   Particle ID:1  Total Energy: 304.48624 GeV  PMTs HIT:  0   PEs:0
12345123451234512345123451234512345123451234710
6710
6710
6710
6710
6710
6710
6710
6710

For the big event that gives me the segmentation fault I get only a long series of 12345. Then it crashes.

I hope the extra info will help.
