Crash report on missing closing parenthesis

[JD557]

Compiler version

3.3.1

Minimized code

I forgot to close some parenthesis and got a compiler crash instead of a compilation error.

Tested in Scala-cli

case class State(x: Int)

def foo[T](state: State)(body: => T): Option[T]
  Option.when(state.x == 0) body

var bar = 0
val state = State(0)

def app: Function1[Int, Unit] =
  new Function1[Int, Unit]:
    def apply(x: Int): Unit =
      foo(state):
        foo(state.copy(x = 5): // Missing ")"
          println("a")
      bar = 2

Output (click arrow to expand)
