Stack overflow error when nesting a case class and its companion object inside a method

Compiler version

I have just raised this issue for scala 2.12 and 2.13 (https://github.com/scala/bug/issues/12435) but it seems to also apply to scala 3.

Minimized code

def method(): Unit = {
  final case class Person(name: String)
  object Person {
    val me = Person("Cameron")
  }
  val _ = Person.me
}
method()

Output

java.lang.StackOverflowError

Expectation

Expected output is Unit. This happens if I change the val to a lazy val or def. I also get the expected output if I use the “new” keyword to construct the instance of my case class

[som-snytt]

There is some speculation on the scala 2 issue. I think a good compromise for common use cases may suffice.

Minimized to

object Person {
  def apply(): Unit = ???
  val me = Person.apply()
}
@main def app = Person.me
