We are getting infinite loop when geantino is shooted from the middle in x-direction in the tube, that has non-zero Rmin and is divided equidistantly in Phi axis; and also in some other case. The concrete examples (modified N02 detector construction class + test macro and test output) are provided in: /afs/cern.ch/user/i/ivana/public/g4replica/case1 /afs/cern.ch/user/i/ivana/public/g4replica/case1 The problem has been already reported with the geant4 1.0 release (but not via Web report system), but it persists in 1.1 release.
This problem is already opened as problem-report #44. It's still under investigation. Thanks for providing us a testbed example. *** This bug has been marked as a duplicate of 44 ***
