Views with parallel collections are buggy #5525

scabug · 2012-02-27T00:40:11Z

In 2.9.1 REPL, repeating the exact same "find" query twice gives different results. It only does this when using both ".par" and ".view".

scala> val f : Int => Int = _ + 10
f: Int => Int =

scala> List(1,2,3).par.view.map(f).find(_ > 11)
res11: Option[Int] = Some(12)

scala> List(1,2,3).par.view.map(f).find(_ > 11)
res12: Option[Int] = None

Is indeed reproducible in 2.9.1 - both in repl and outside repl.

Yes, I can reproduce in 2.9.1, but I can't reproduce it in 2.10 nightly.
