(From C. Green, CDF, FNAL) Hi, In G4Polycone.cc, enclosingCylinder is not cleaned up in the destructor, leading to a memory leak. Thanks, Chris.
Fixed in tag "geom-solids-specific-V01-01-01" for source/geometry/solids/specific. It will be included in Geant4 2.0 public release. Thanks for reporting it.
