|---|---|---|---|
| Product: | Geant4 | Reporter: | Ivana.Hrivnacova |
| Component: | processes/hadronic | Assignee: | dennis.herbert.wright |
| Status: | RESOLVED FIXED | ||
| Severity: | normal | ||
| Priority: | P2 | ||
| Version: | 8.1 | ||

Fixed by Alex Howard. The fix will be included in the next patch or release.
Until then, you can fix the code yourself by modifying
geant4/source/physics_lists/lists/include/LBE.icc
as follows:
add these three lines:
#include "G4MesonConstructor.hh"
#include "G4BaryonConstructor.hh"
#include "G4IonConstructor.hh"
then change the following three methods to look like:
template<class T> void TLBE<T>::ConstructMyMesons()
{
// mesons
G4MesonConstructor mConstructor;
mConstructor.ConstructParticle();
}
template<class T> void TLBE<T>::ConstructMyBaryons()
{
// baryons
G4BaryonConstructor bConstructor;
bConstructor.ConstructParticle();
}
template<class T> void TLBE<T>::ConstructMyIons()
{
// ions
G4IonConstructor iConstructor;
iConstructor.ConstructParticle();
}
finally, in method
template<class T> void TLBE<T>::ConstructGeneral()
replace
if (theDecayProcess->IsApplicable(*particle))
with
if (theDecayProcess->IsApplicable(*particle) && !particle->IsShortLived())

We are getting break when using the LBE physics list within Geant4 VMC application. I have tested this physics list within Geant4 novice N04 example (by just changing QGSP with LBE in exampleN04.cc) and could reproduce the crash, see the gdb backtrace below.
