Trying out K2 for my Android project (which is open source, available here: https://github.com/smileidentity/android). It is throwing

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering
The root cause java.lang.RuntimeException was thrown at: org.jetbrains.kotlin.backend.jvm.codegen.FunctionCodegen.generate(FunctionCodegen.kt:51)

Looks like it's an OOM which you can fix by increasing your max heap size (org.gradle.jvmargs=-Xmx=${n}G ).

[vanshg]

Should that be necessary at all though? The code is not doing anything fancy

[mbonnin]

Agreed. And if necessary to trade memory for performance, it should be documented somewhere

[vanshg]

I wonder if it is worth filing something for this
