An exception is reported when tests are run with the QGS_BIC physics list in ATLAS setup. The Geant4 version used is 9.4 patch03 with a small set of customisations (signal handler, RK stepper) and a few additional recent fixes for urgent problems. The job reports the following: G4AtlasAlg SUCCESS G4AtlasAlg: Event num. 4 start processing G4BinaryCascade::GetIonMass() - invalid (A,Z) = (0,2) G4BinaryCascade::GetIonMass() - giving up *** G4Exception: Aborting execution *** Py:AtlasG4_trf INFO AtlasG4_trf has completed running of Athena with exit code -6. A full log of the job is temporarily available at https://atlas-rtt.cern.ch/prod/rtt/rel_5/devval/build/x86_64-slc5-gcc43-opt/offline/SimCoreTests/QgsBicTest/QgsBicTest_log
This was corrected in geant4 9.5 and was not a simple bugfix.
