Thank you Ben for your reply.

Well, I definitely have something wrong in my Geant4. Since it is easier to show what is happening than to explain, here you have my steps and attachments:

1) make clean
2) source /home/marco/geant4.9.3/ (see file setGeant4_9.3.txt)
3) make
4) ldd application (see lddGeant4_9.3.txt)
5) make clean
6) source /home/marco/geant4.9.3.p01/ (see file setGeant4_9.3.p01.txt)
7) make
8) ldd application (see lddGeant4_9.3.p01.txt)

As you can see in step 8, the patched version is getting libraries from the Geant4 9.3 folder, but since the patched version is giving correct results (comparing with other computers), I must assume that when I installed Geant4 9.3.p01 some libraries were put in Geant4 9.3 (Geant4 9.3 is giving wrong results).

To make my problem even clearer, these were my steps in installation:

1) I already had Geant4 9.3 since February or so
2) I installed Geant4 9.3.p01 in a different folder
3) When the installation finished, I realized that I had forgotten to verify printenv | grep G4 and there were the environment variables from Geant4 9.3
4) I erased the two folders
5) I installed Geant4 9.3
6) I installed Geant4 9.3.p01

In theory, the two versions of Geant4 should only share the CLHEP libraries.

My path is defined in .bashrc with:

export G4WORKDIR=~/g4work

export ROOTSYS=~/ROOT/root
export PATH=$ROOTSYS/bin:$PATH

I do the source command manually to choose which version of Geant4 I want to run.
