Async assignment to a lazy local var causes Xcode 15.3 compiler crash

Further whittling down, the compiler crash still occurs if waitTillPaired() is simplified to:

    func waitTillPaired() async throws {
        lazy var stateChanges = await self.state.obtainSubscription().makeAsyncIterator()
        let state = await stateChanges.next()
    }

The code compiles correctly if I remove lazy or if I change AsyncState from actor to class.

So this may be an edge case with lazy evaluation of actor owned instance variables.
