The shared libraries for HP are made using CC instead of aCC. This has the effect that global objects (for example G4cout) are not initialized and the program linked against these libraries crashes. Change in makeshlib.sh CC -b -o $libso $objs with aCC -b -o $libso $objs
Problem fixed and committed to HEAD of the CVS repository: Checking in makeshlib.sh; /afs/cern.ch/sw/geant4/cvs/geant4/config/makeshlib.sh,v <-- makeshlib.sh new revision: 1.3; previous revision: 1.2 done Will be included in future releases and reference tags. Thanks.
