the error isn't always the same, but it's always on the same call to actor

[elizarov]

Any clue under what conditions it reproduces?

[bj0]

not really, it's always the same place, onCreateView in a Fragment calls this extension:

inline fun <T : View> T.onClick(disableDuring: Boolean = false, noinline action: suspend T.() -> Unit) {
    val actor = actor<Unit>(UI) {
        for (event in channel) {
            try {
                if (disableDuring) isEnabled = false
                action()
            } finally {
                if (disableDuring) isEnabled = true
            }
        }
    }

    setOnClickListener { actor.offer(Unit) }
}

the call to actor throws, and sometimes it's the arity error, sometimes it's a 'calling method on null object' error. I had copied several of them but deleted them. Whenever it happens I just gradle clean and rebuild (sometimes have to do it twice) and it works again

It is definitely a bug in incremental compilation somewhere. It would be extremely helpful if you find what changes reproduce it.

not sure how to tell, the project is pretty big and it seemed to happen everytime I recompiled yesturday
