It seems the G4RayTracer is not working with version 5.2 and gcc3.2. This can be demonstrated with example/novice/N03, with the following commands: ... /vis/scene/create /vis/scene/add/volume /vis/sceneHandler/create RayTracer /vis/viewer/create /vis/rayTracer/trace These will lead to segmentation fault.
RayTracer needs to be fixed with respect to recent massive change in G4RunManager, and also on-going RunManager restructering. Fixing RayTracer is on schedule and expected by the end of month.
Fix is committed to the CVS with raytracer-V05-02-00 tag and proposed to the system testing team. Thank you for your report.
