Ready for this? This is a good one.

scala> Vector() ++ Iterator(1)
res9: scala.collection.immutable.Vector[Int] = Vector(1)

scala> Vector() ++ Iterator(1, 2)
res10: scala.collection.immutable.Vector[Int] = Vector(1, 2)

scala> Vector() ++ Iterator(1, 2, 3)
res11: scala.collection.immutable.Vector[Int] = Vector()

was fine in 2.11.0-M5.

I can't seem to find another combination of types besides Vector + Iterator on which it fails

OlegYch and datura on #scala figured out the culprit appears to be scala/scala@4234b34#diff-59f3462485b74027de4fd5e9febcc81b from the fix for #7725. case _ => super.\+\+(that) should be case _ => super.\+\+(again)
