Zack have reprorted the crash in G4VGammaDeexitation due to usage of NULL pointer. The tar file is available: /afs/cern.ch/user/a/adotti/public/SimplifiedCalo.tgz with the exercise.g4 macro file and FTFP_BERT Physics List. Similar bugs are reported in HyperNews. Dennis, you can assign the bug to me, because we are discussing gamma evaporation now and I am in subject. Vladimir
The bug is not reproduced anymore.
