Transformation failure in objects

[ReneeVandervelde]

getAndUpdate Seems to fail when the parent class is an object:

object Example {
    private val atomic = atomic("test")

    fun update() {
        atomic.getAndUpdate { "$it !" }
    }
}

Results in the following compilation error:

Failed to transform: java.lang.ArrayIndexOutOfBoundsException: -1

Changing the declaration to class will compile successfully.

This seems to have been reported before in #94 as a problem with companion objects, which was closed but never resolved.

Hi,
I have the same error with a bit different code:

private val top = atomic<Int?>(null)

fun main() {
    top.update { 0 }
}
