Summary: requesting element from 0-length vector causes crash
Product: Geant4 Reporter: Daren Sawkey <daren.sawkey>
Component: processes/hadronic/models/cascadeAssignee: dennis.herbert.wright
Status: RESOLVED FIXED    
Severity: normal    
Priority: P4    
Version: 10.2   
Hardware: All   
OS: All   

Description Daren Sawkey 2016-08-30 01:55:22 CEST 
In the file
processes/hadronic/models/cascade/cascade/src/G4InuclCollider.cc
there are two calls to
checkOutput.getOutgoingNuclei()[0]
(lines 355 and 360 of version 10.2.patch2)

The std::vector checkOutput.getOutgoingNuclei() can have no elements and thus these calls cause a segmentation fault.

Added checks against zero entries.
