During the compilation of the iort_therapy example, several unused variables were detected using the clang trunk as compiler. One of them even had a non-english name: geant4.9.6.p02/examples/advanced/iort_therapy/include/Collimator50BeamLine.hh:149:23: warning: private field 'solidsottrazione' is not used [-Wunused-private-field] G4SubtractionSolid* solidsottrazione;
IORT_therapy, as released with Geant4 10.0, does not show the problem (at least in my platform/build). The bug report seems to be based on the version 9.6.p02, rather than on 10.0. In particular, the file include/Collimator50BeamLine.hh does not have any private field called G4SubtractionSolid* solidsottrazione; For the time being, I am going to mark the bug report as "INVALID". Please feel free to re-open it if the problem does actually occur also with Geant4 10.0.
