My application is a simple neutron detector with a gas chamber. I wanted to change the pressure/density or the material of the gas from the interface. I followed the implementation of setMaterial of TestEm7.
With my application after I changed the material from the interface and try to start a new run it fails and send a segmentation fault (with gdb):
0x00007ffff40a3a0b in G4NeutronHPData::DoPhysicsVector(G4NeutronHPVector*) () from /home/john/geant4/geant4.9.3/lib/Linux-g++/libG4processes.so ->my physics list have the HP models.
Then I tried to put a physics list with HP such as LHEP_PRECO_HP in the TestEm7. Oh surprise I got the exact same result.
There might a problem in the G4NeutronHPData::DoPhysicsVector method to update the physics, or I really did something wrong and I'll be glad to understand what.
