If compiled together with TraversableOnce.BufferedCanBuildFrom and Builder I see this issue:

./scala-scala/src/library/scala/collection/Iterator.scala:31: error: object creation impossible, since def apply: (from: [+hk$0] => scala.collection.Iterator[hk$0])scala.collection.mutable.Builder[A, scala.collection.Iterator[A]] is not defined

If compiled in isolation:
