This crashes with IllegalStateException: Start/end imbalance

@Composable fun A() = Row { if (true) return }

It does not happen if I remove the if or if I use return@Row

Please file a bug for this

It looks like the handling of inline functions with non-local returns isn't fully there yet

@Adam Powell
We are facing this too. May it be that this has no attention because the issue is closed?
To me this looks very serious, in our code base we have crashes due to this at at least 50 places where we do an early return when collecting flows.

Will open an issue. Got a repro

[Paul Woitaschek]

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            Column {
                if (true) return@Column
            }
        }
    }
}

To emphasize: To me that’s a pretty big bad bug ^^

@Leland Richardson [G] sorry to be annoying but to me this seems really critical & hotfix worthy
