Hello,
I have seen that the new crash in the qa macro reco_complete_tpc comes from MVD code, in particular PndMvdStripClusterTask::CalcMeanCharge.
It seems for some strip digi the charge is zero, then at line 485 of PndMvdStripClusterTask.cxx one has divison by zero.
Would it be possible to fix it?
Thanks in advance
here you are the gdb log:
