ROOT Version: 6.16/00
Platform: Centos 7 lxplus
Compiler: gcc (GCC) 7.3.0

Dear All,
I am running geant4 simulation and writing a root tree with histograms and tree. I have checked geometry overlaps and it all came out OK ! But when I try to run the program, I get the following break segmentation violation and I am not sure of the cause. Can anyone please help to fix this as I am unable to finish the run every time .Thank you very much in advance,
