Backend Internal error: Exception during IR lowering when using inline fun with crossinline and anonymous object defined in another cell

[ileasile]

Original error is: Local class should have its name computed in InventNamesForLocalClasses

Execute two cells:

class R {
    val x: Int = 1
}
inline fun R.t(crossinline action: (R) -> Int) = object {
    val y get() = action(this@t)
}

and

R().t {it.x * 2}

Result:

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:50)

Even simpler reproducer:

inline fun test() {
    run {}
}

and in a separate cell

test()
