Sorry, I was on vacation to answer you sooner. Thank you for your feedback and posting to this forum.

I am afraid that I have never tried the G4OpBoundary process with anything but simple CSG volumes (as opposed to BREPS). Why a simple hexagon is a BREP in Geant4 is a mystery to me?

But why it doesn't work would require me to know where the looping happens (in G4OpBoundaryProcess?). - I don't know when I can attend to this bug report but I will certainly forward this problem to the geometry experts because I suspect the problem has to do with what normal is returned by the call to GetLocalExitNormal or GetLocalToGlobalTransform()
