UBSAN IBs show that we have runtime error [a] coming from
return (data_[layer][channel] >> bx) & 1;
at https://github.com/cms-sw/cmssw/blob/master/L1Trigger/CSCTriggerPrimitives/src/PulseArray.cc#L34 . [b] shows that it was generated from https://github.com/cms-sw/cmssw/blob/master/L1Trigger/CSCTriggerPrimitives/src/CSCAnodeLCTProcessor.cc#L688-L694 whenfirst_bx_layer
become0
.@cms-sw/l1-l2 , can you please review this code and provide a fix ( may be loop should terminate at
first_bx_layer==0
)?[a] https://cmssdt.cern.ch/SDT/jenkins-artifacts/ubsan_logs/CMSSW_14_2_X_2024-10-14-2300/logs/05/0530d321b0724e89cb472942594cd256/log
