Realm -SNAPSHOT seems incompatible with Kotlin 1.7.2

Hi!

I came across this issue: https://github.com/realm/realm-kotlin/issues/1002 I seems to have a similar error but WITH the fix in place. I did update my project with Kotlin 1.7.20-RC and my realm module fails with

e: org.jetbrains.kotlin.backend.common.CompilationException: Back-end: Please report this problem https://kotl.in/issue

Now I did setup my project to use the realm 1.2.0-SNAPSHOT and I’m pretty sure it’s used because the error originate from IrUtils.kt:323 which if I understand correctly is what was introduced to fix issue 1002.

Is this another problem or something else?

Thanks in advance 😄

A small update. After the announcement of Kotlin 1.7.20 and Kotlin Multiplatform Beta, we made the decision to migrate the library to the new memory model. This has the following implications:

• The minimum Kotlin version supported is now 1.7.20.
• We only support the new memory model (default in 1.7.20).
• Due to this, we were able to update to Ktor 2, including adding support for Apple Silicon targets.
• All of this was merged into master and is now available as a 1.4.0-SNAPSHOT. You can see the full CHANGELOG here. Instructions on using a SNAPSHOT release are here.
• Realm Kotlin 1.3.0 and below still support Kotlin 1.7.10 and lower, including the old memory model.

Feedback would be much appreciated if anybody can try this release. We will also be doing our own testing and then a full 1.4.0 release will be created next week unless we encounter any unforeseen bugs.

Looks like in order to solve this issue i have to add this to settings.gradle.kts

pluginManagement {
    resolutionStrategy {
        eachPlugin {
            if (requested.id.namespace == "io.realm") {
                useModule("io.realm.kotlin:gradle-plugin:1.4.0-SNAPSHOT")
            }
        }
    }
    repositories {
        maven("https://oss.sonatype.org/content/repositories/snapshots")
        gradlePluginPortal()
    }
}

I believe this should be in the README. I’ll make a PR regarding this
