I use last release: geant4.8.0. I have Scientific Linux 4.2, ggcc (GCC) 3.4.3 20041212 (Red Hat 3.4.3-9.EL4). Compilation of geant was o.k., without errors, the compilation exmaples/novice is also o.k., but if I try to exec e.g. exampleN01 I have segmanetation fault message. I made compilation with G4DEBUG option and using gdb I have: (gdb) exec-file exampleN01 (gdb) run Starting program: /geant4.8.0.p01/bin/Linux-g++/exampleN01 Using host libthread_db library "/lib/tls/libthread_db.so.1".

This kind of run-time errors are usually related to either incompatible libraries used (i.e. libraries built on a different system/compiler than the one used to build the final application), or to a buggy installation/version of the specific compiler in the system. If the latter case, I suggest to reinstall the gcc compiler as alternate and rebuild CLHEP and Geant4 with the new configuration. See in: http://geant4-hn.slac.stanford.edu:5090/HyperNews/public/get/installconfig/428/3/1/1/1/1.html for a quick recipy on how to build/install the compiler and configure your environment.
