segfault on simple kernel

[owlet-labs]

The issue is pretty self-explanatory: I write a simple job based on demo code, I verify my GPU is recognized, and the context is properly initted-- but when I execute the code, the computatin fails with a segfault... I have an intuition that the issue is coming around compilation time for the kernel, but I don't really know.

Any hints to further debug this issue?

  import scalacl._

  implicit val context = Context.best

  println(context.context)
  println("stage 0")
  val a = CLArray[Int](1, 2, 3)
  val v = 10
  println("stage 1")
  val clFunction: CLFunction[Int, Float] = (x: Int) => {
    x * 2.0f * v
  }
  println("stage 2-- expect FAIL")
  val clResul = a.map(clFunction).toArray
  println(" we will probably not get to stage 3 : (")
}
