I am using 4.6.2p02 version. I get segmentation fault after I start a /geometry/test/recursive_test. Idle> /geometry/test/recursive_test GeomTest: no daughter volume extending outside mother detected. GeomTest: no overlapping daughters detected. GeomTest: no daughter volume extending outside mother detected. GeomTest: no overlapping daughters detected.

If I remove this volume, the problem disappears. If I add the same shape but with the side facing down, the problem doesn't appear. Also, the problem appears with semispheres with minradius>0, independently on their orientation. I didn't have this problem with version 4.6.2p01. #0 0x40bab202 in G4GeomTestSegment::PatchInconsistencies(G4GeomTestLogger*) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #1 0x40bab10d in G4GeomTestSegment::FindPoints(G4GeomTestLogger*) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #2 0x40baafed in G4GeomTestSegment::G4GeomTestSegment(G4VSolid const*, Hep3Vector const&, Hep3Vector const&, G4GeomTestLogger*) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #3 0x40bb0723 in G4GeomTestVolume::TestOneLine(Hep3Vector const&, Hep3Vector const&) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #4 0x40bb0116 in G4GeomTestVolume::TestCartGrid(Hep3Vector const&, Hep3Vector const&, Hep3Vector const&, int, int) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #5 0x40baf260 in G4GeomTestVolume::TestCartGridX(int, int) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #6 0x40baf1dd in G4GeomTestVolume::TestCartGridXYZ(int, int, int) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #7 0x40baf541 in G4GeomTestVolume::TestRecursiveCartGrid(int, int, int, int, int) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #8 0x40baf4bf in G4GeomTestVolume::TestRecursiveCartGrid(int, int, int, int, int) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #9 0x40baf4bf in G4GeomTestVolume::TestRecursiveCartGrid(int, int, int, int, int) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #10 0x40ba87f1 in G4GeometryMessenger::RecursiveGridTest() () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #11 0x40ba7db6 in G4GeometryMessenger::SetNewValue(G4UIcommand*, G4String) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4navigation.so #12 0x40dbaaa2 in G4UIcommand::DoIt(G4String) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4intercoms.so #13 0x40dd376e in G4UImanager::ApplyCommand(char const*) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4intercoms.so #14 0x40dd3311 in G4UImanager::ApplyCommand(G4String) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4intercoms.so #15 0x401dac20 in G4UIterminal::ExecuteCommand(G4String) () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4UIbasic.so #16 0x401da895 in G4UIterminal::SessionStart() () from /SS/geant4.6.2.p02/lib/Linux-g++/libG4UIbasic.so #17 0x0804d512 in main ()
