=== What steps will reproduce the problem (please be specific and use wikiformatting)? ===

abstract class A {
  def get: Int
}

class Base(a: A)

abstract class Derived extends Base(new A { def get = Derived.this.get }) {
  def get: Int
}

=== What is the expected behavior? ===
An error like "cannot reference Derived.this before the super constructor call"

=== What do you see instead? ===
A compiler crash. Here's the exception in the REPL:

Exception in thread "main" java.lang.Error: no-symbol does not have owner
