Jetpack Compose version:

androidx.compose.compiler:compiler:1.5.6
androidx.compose:compose-bom:2023.10.01

Jetpack Compose component used: compiler and runtime

Android Studio Build: Hedgehog | 2023.1.1 Build #AI-231.9392.1.2311.11076708, built on November 9, 2023

Kotlin version: 1.9.21

I encountered this crash upgrading Kotlin from 1.9.20 to 1.9.21. When I switched our project to Kotlin 1.9.21, one of our compositions started to crash.

In this view I’ve isolated the problem:

import android.annotation.SuppressLint
import android.content.Context
import androidx.compose.foundation.text.BasicText
import androidx.compose.runtime.Composable
import androidx.compose.runtime.ReadOnlyComposable
import androidx.compose.runtime.getValue
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.platform.AbstractComposeView

@SuppressLint("ViewConstructor")
class IsolatedView(
  context: Context,
) : AbstractComposeView(context) {
  @Composable
  @ReadOnlyComposable
  fun key1(): String = "key1"

  @Composable
  override fun Content() {
    val label by remember(key1()) {
      mutableStateOf("hello")
    }
    BasicText(text = label)
  }
}

import app.cash.paparazzi.Paparazzi
import org.junit.Rule
import org.junit.Test

class IsolatedTest {
  @get:Rule val paparazzi = Paparazzi()

  @Test fun test() {
    paparazzi.snapshot(IsolatedView(paparazzi.context))
  }
}

This sample uses Paparazzi to snapshot a composition in a test case. I don’t believe Paparazzi is necessary to reproduce this.

I believe the problem is that I’m using the result of a @Composable function as the argument to remember().
