Some patches will cause an out of bounds exception (which would crash if directly applied to any tables). This PR adds two test scenarios that show the behavior.

I am not sure how to fix this, but wanted to share the results of my research.

I also generated a couple of more test cases which will cause the same error:

[0, 7, 3, 7, 4] -> [9, 9, 1, 8, 4, 7, 2, 7, 7, 5] 
[6, 2, 2, 3] -> [10, 4, 8, 3, 6, 2] 
[7, 0, 8, 1, 3, 9, 7] -> [7, 7, 4, 8, 6, 9, 5, 1, 3] 
[7, 0, 0, 2] -> [5, 4, 8, 2, 10, 5, 7, 9, 0, 10]

Tests that show the problem are my favourite! Thank you for doing this.

It would be good if you could revert the changes to the Xcode project definition before I merge this in.

I start to think this might be caused by duplicates in the target 🤔
