Coroutines crash when upgrading to Kotlin 1.3.30 - kotlin.coroutines.intrinsics.CoroutineSingletons cannot be cast to java.lang.Boolean #1091

ZakTaccardi · 2019-04-12T15:26:09Z

The following test crashes with the following versions:

Kotlin 1.3.30 (does not crash with 1.3.21)
Kotlin Coroutines 1.1.1

package com.crossinlinebugtest

import kotlinx.coroutines.CoroutineScope
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.channels.Channel
import kotlinx.coroutines.channels.ReceiveChannel
import kotlinx.coroutines.channels.consumeEach
import kotlinx.coroutines.channels.sendBlocking
import kotlinx.coroutines.launch
import org.junit.Test

class CrossinlineBugTest {

    @Test
    fun crossinlineTest() {
        val scope = CoroutineScope(Dispatchers.Unconfined)
        val channel = Channel<Unit>()

        scope.launchCrossinlineFunction(channel)

        channel.sendBlocking(Unit)
    }

    internal inline fun CoroutineScope.launchCrossinlineFunction(
        receiveChannel: ReceiveChannel<Unit>,
        crossinline block: (String) -> Unit = { println(it) }
    ) {
        launch {
            receiveChannel.consumeEach {
                block("String")
            }
        }
    }
}

Removing inline and crossinline fixes the issue.

internal fun CoroutineScope.launchCrossinlineFunction(
        receiveChannel: ReceiveChannel<Unit>,
        block: (String) -> Unit = { println(it) }
    ) {
        launch {
            receiveChannel.consumeEach {
                block("String")
            }
        }
    }

Crash does not occur when you specify the default lambda.

@Test
fun crossinlineTest() {
    val scope = CoroutineScope(Dispatchers.Unconfined)
    val channel = Channel<Unit>()
    scope.launchCrossinlineFunction(channel) { println("Specifying the default param fixes this issue") }
    channel.sendBlocking(Unit)
}
internal inline fun CoroutineScope.launchCrossinlineFunction(
    receiveChannel: ReceiveChannel<Unit>,
    crossinline block: (String) -> Unit = { println(it) }
) {
    launch {
        receiveChannel.consumeEach {
            block("String")
        }
    }
}

inline and crossinline should work 👍

Note 1: I tried upgrading to 1.2.0-alpha2 and still had the issue.
Note 2: Did not experience the issue in 1.3.21

elizarov · 2019-04-12T16:18:01Z

Which kotlin version it worked? Seems to be a compiler problem. I've reported it here: https://youtrack.jetbrains.com/issue/KT-30997

ZakTaccardi · 2019-04-12T16:44:29Z

@elizarov Thanks! I have updated the issue. It now contains standalone code that is easy to reproduce.

Specifically, it's the suspend with crossinline and a default lambda parameter that is executed within a .consumeEach { .. }

ilmirus · 2019-04-12T17:26:32Z

@ZakTaccardi It seems, the latest 1.3.30 release candidate contains the fix. Can you, please, verify this?
To check, use 1.3.30-eap-164 from 'https://dl.bintray.com/kotlin/kotlin-eap' repository.

ZakTaccardi · 2019-04-12T22:18:26Z

@ilmirus I actually am unable to. The Kotlin EAP is in a different Maven repository that I am unable to use due to work network proxy restrictions

qwwdfsad · 2019-04-13T12:42:38Z

I am closing this one, it is a compiler bug (https://youtrack.jetbrains.com/issue/KT-30997) that will be fixed in upcoming 1.3.31.
Thanks for the report with a reproducer!

ZakTaccardi · 2019-04-26T19:26:04Z

Note: it seems the fix for this issue introduced a regression. See https://youtrack.jetbrains.com/issue/KT-31242
