Description alexander.howard 2007-07-02 17:44:05 CEST 
G4hLowEnergyLoss contains and uses undefined variables leading to floating point exceptions and crashes (and presumably unstable/inaccurate behaviour):

Comment 1 Sebastien Incerti 2009-01-23 12:29:16 CET 
The problem is expected to have been solved with tag emlowen-V09-01-18.
For the moment, I could not reproduce it (Geant4 9.2, SL4.5, gcc 3.4.6-8).
Comment 2 Sebastien Incerti 2009-02-20 11:54:05 CET 
More FPE were found (see EM forum item 893).
tag emlowen-V09-02-15 was provided to fix these.
