Description John Apostolakis 2012-03-26 14:17:25 CEST 
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.

Comment 1 Gunter.Folger 2012-05-11 10:49:39 CEST 
This was corrected in geant4 9.5 and was not a simple bugfix.
