Description w.stiller 2005-02-01 01:54:02 CET

Installation of Geant 4.7.0 worked fine (according to the log). The system is a
dual Opteron AMD 64 bit system running SuSe Linux 9.1, the compiler is gcc
3.3.3. Compilation of the examples gives no errors/warnings, but the minute the
run starts the examples crash with a segmentation fault:

Start Run processing.
=====================================
  G4EventManager::ProcessOneEvent()
=====================================
1 primaries are passed from G4EventTransformer.
!!!!!!! Now start processing an event !!!!!!!
### pop requested out of 1 stacked tracks.

Segmentation fault


It is the same for the other examples. I found an message in on the HyperNews
asking if this is a problem with AMD 64bit, but there is no answer posted yet.
All examples worked fine when I installed version 4.6.2 some time ago. Thanks
for your help.

It would be useful if you can attach a debug trace of the segmentation fault.
Note: we're NOT officially supporting 64 bit AMD architectures, as such we do not
have possibility to test or verify what reported. The more information you can
provide the better it is for us to try understanding the problem. Thanks.

Try upgrading to Geant4 7.1 which has been tested on 64-bits systems.
