    [counters] RuntimeStats: fix wrong bookkeeping when dynamically changing counters · 244dd002
    cbruni authored
    RuntimeTimerScopes always subtract their own time from the parent timer's
    counter to properly account for the own time. Once a scope is destructed it
    adds it own timer to the current active counter. However, if the current
    counter is changed with CorrectCurrentCounterId we will attribute all the
    subtimers to the previous counter, and add the own time to the new counter.
    This way it is possible to end up with negative times in certain counters but
    the overall would still be correct.
