Description a.ramazani 2012-12-31 13:13:22 CET
There are identical sub-expressions 'trk1.GetDefinition() == G4Neutron::Neutron()' to the left and to the right of the '||' operator. g4scatterer.cc 140


Error:
	   if(( trk1.GetDefinition() == G4Neutron::Neutron() ||
	        trk1.GetDefinition() == G4Neutron::Neutron() ) &&
Correct:
	   if(( trk1.GetDefinition() == G4Neutron::Neutron() ||
	        trk2.GetDefinition() == G4Neutron::Neutron() ) &&

I used The Best C++ static code analysis Tools "PVS-Studio 4.77" under Visual Studio 2012 to analyze the Geant4.9.6 code
There is many warnings and performance optimization so I recommend using PVS-Studio

Please correct me if I am wrong 
Thanks in Advance.

Fixed in development version.
The only problem this causes will be a performance penality, as a shortcut may not be taken. Shortcut is to avoid calculation of cross section, when it is easy to estimate that particles will not interact.
