Question Problem with G4SteppingManager::Stepping():DefinePhysicalStepLength() 

Forum: Event and Track Management
Date: 09 Apr, 2008
From: Yapeng Zhang <y.p.zhang@impcas.ac.cn>

Hi, everybody,

I use Geant4.8.1.p02 with gcc 3.4.3, CLHEP 1.9.2.3 and the GDML_2_9_0.
There is no error in compiling process. I can get a proper geometric structure of detector in both OGLIX and Wired environment. 
But when I run the command "/run/beamOn 1" in Idle state, I get the following crash messages. 
Then, I found the crash point is  at "G4SteppingManager::Stepping():DefinePhysicalStepLength()".
The following is the values of some private variables of G4SteppingManager class before runing the Stepping():DefinePhysicalStepLength()function,  
"physIntLength  1.79769e+308,  fCondition  7117256, fGPIlSelection  536870912".
