Error: illegal pointer to class object gClient 0x0 497

Hello All,

I've compiled a C++ application on Rocks 5.1 HPC cluster (CENTOS-5.2) with Intel-10.1.018 C++ compiler. The compilation was smooth with some warnings.

But during execution of the benchmark it failed with following message:

=== much_sim.C : Loading libraries ...
Error: illegal pointer to class object gClient 0x0 497 /opt/bench-intel/cbmroot/gconfig/basiclibs.C:8:
*** Interpreter error recovered ***
Error in : BadAtom (invalid Atom parameter) (XID: 39, XREQ: 18)

The basiclibs.C file contain following content:

# cat gconfig/basiclibs.C
// $Id: basiclibs.C,v 1.1.1.1 2005/06/23 07:14:09 dbertini Exp $
//
// Macro for loading basic libraries used with both Geant3 and Geant4

void basiclibs()
{
gSystem->Load("libGeom");
gSystem->Load("libGeomPainter");

gSystem->Load("libVMC");
gSystem->Load("libPhysics");
gSystem->Load("libEG");
gSystem->Load("libEGPythia6");
gSystem->Load("libPythia6");
gSystem->Load("libPluto");
gSystem->Load("libMinuit");
gSystem->Load("libMLP");

}

Any hint what's wrong going here?

I'm not familiar enough with the application to give any hints here. Hopefully someone else who's more familiar can chip in. I did some googling on that error message, and it does show up in other situations, but it's hard for me to say which if any of them may apply in this case.
