&(*x)doesn't clone the data (that pattern has used for theclone()function forgoka.InputStatsandgoka.OutputStats) into a new instance because it is simplified tox. (This can be detected by staticcheck SA4001) So, it has made data race condition when a cloned stats is used. We have observed this in Goka web monitor and other places where it is usingView.Stats.This can be reproduced with a goka web monitor enabled application by turning on the Go race detector
