Guys, do you know whether theres is a way to tell kotlin compiler NOT to optimise some `var`s?

Here's my example on JVM (#coroutines) :

fun <T> ReceiveChannel<T>.reduce(reducer: (T, T) -> T) = produce<T>(Unconfined) {
    var prev: T? = null
    for (elem in this@reduce) {
        if (prev == null) {
            prev = elem
            send(elem)
        } else {
            val new = reducer(prev, elem)
            prev = new
            send(new)
        }
    }
}

When run in debug mode everything works fine. However when run normally reading from prev always returns null - I suppose some "optimisation" is taking place in non-debug builds.
