    Hi Femming and Kris,

the GDB output gives:

Looks like trouble is at

BrZdcSlewCalModule::Finish (this=0x8ae33b0) at BrZdcSlewCalModule.cxx:329

But here is a copy from that module (with line numbers):

326: fCalibration->SetComment ("Slewpar1", "Generated by
BrZdcSlewCalModule: fit with a pol3 function");

327: fCalibration->SetComment ("Slewpar2", "Generated by
BrZdcSlewCalModule: fit with a pol3 function");

328: fCalibration->SetComment ("Slewpar3", "Generated by
BrZdcSlewCalModule: fit with a pol3 function");

329: fCalibration->SetComment ("Slewpar4", "Generated by
BrZdcSlewCalModule: fit with a pol3 function");

330: fCalibration->SetComment ("Slewpar5", "Generated by
BrZdcSlewCalModule: fit with a pol3 function");

and it doesn't give any clues why BE shows up, so m.b. Kris
is right, but I couldn't figure out at the moment any array
overflows in the code... It worked perfectly not long time
ago, and I haven't changed nothing in there.

Andrei.
