Question Problem with physics lists

Hello all,

I am using a slightly modified version of the extended example "Radioactive decay" from geant 4.8.1p01 
and experiencing problems with the hadron physics. The exrdmPhysicsList.cc file was only changed to include LHEP_PRECO_HP:

#include "HadronPhysicsLHEP_PRECO_HP.hh"

and

void exrdmPhysicsList::SelectPhysicsList(const G4String& name)
{
  if (verboseLevel>1) {
    G4cout << "exrdmPhysicsList::SelectPhysicsList: <" << name << ">" << G4endl;
  }
  // default  Had physics
  if (name == "Hadron") {
    if (hadPhysicsList) delete hadPhysicsList;
    hadPhysicsList = new exrdmPhysListHadron("hadron");
  .....
  } else if (name == "LHEP_PRECO_HP") {
    if (emPhysicsList) delete emPhysicsList;
    emPhysicsList = new exrdmPhysListEmStandard("std-h-em");
    if (hadPhysicsList) delete hadPhysicsList;
    hadPhysicsList = new HadronPhysicsLHEP_PRECO_HP("std-hadron");
  .....
 
The problem is that whenever I try to use any physics besides "Hadron", I get the following error:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1208150336 (LWP 16642)]
0x081f4b18 in G4VEnergyLossProcess::GetMeanFreePath ()

The physics libraries have been built, so I'm not really sure what the problem is. Any help would be greatly appreciated.

Thanks,
