in SDK 8.3.0 in fr955, fr245 I have a glance, and (for demonstration purpose) the following code in getGlanceView:
var a = 0;
var b = 1 / a;
When I run the glance it crashes as expected, but the interesting thing is what's left in the simulator:

This is a functional text input something. I can move up/down, choose letters, which are added on the left, etc :)
