Edit: this only seems to happen with OVAL. RECTANGLE doesn't make it crash.

Start with CropOverlayView.java at drawBackground around line 635 and trace its call from onDraw around line 579. Reproduce the crop activity on Android P DP3 with an OVAL crop shape, compare it with RECTANGLE, and confirm that oval cropping no longer crashes while drawing.
