Description Vittorio Zecca 2014-06-24 07:42:41 CEST 
Running TestEm6 run02.mac I found that at src/SteppingAction.cc line 91
"analysisManager->FillH1(3,std::log10(thetaMinus*GammaMinus));"
the variable thetaMinus is zero, thus causing the code to compute 
the logarithm of zero.
Putting "assert(thetaMinus);" before that line confirmed my finding.

Hello,

thanks for pointing to the bug. The fix will be in the next patch for Geant4 10.0 and in the new Geant4 release.
