Start with question_controller.go lines 29-32 in the linked lon9/qna commit and inspect how the range variable v is used in the two Related calls. Read the analyzer details in this issue and the referenced code context to determine whether this is a real range-loop pointer problem, mitigated behavior, or desirable behavior. Record the appropriate classification once the finding is understood.
