Open Radar

 
Area:
SceneKit

Summary: 
If hit test is done in a SceneKit scene with nothing but a ARSCNPlaneGeometry in there, the hit test crashes the app. (EXEC_BAD_ACCESS).
The error occurs on iOS 11.3 and Xcode 9.4 by using the ARSCNPlaneGeometry available since ARKit1.5 (which is included in iOS 11.3).
When a "normal" SCNPlane is used for visualising the plane found by ARKit, everything works as expected and the hit test succeeds.

Steps to Reproduce: 
1. Take the attached sample app and execute it
2. Wait until a horizontal plane was detected
3. Then tap on the screen with the red cross in the middle pointing to the plane
4. App crashes :(

Expected Results:
Hit test shall return all nodes which are located in the hit test's direction

Actual Results:
App crashes because of an error during the hit test calculation
