You still need to Tools/Scripts/prepare-ChangeLog -b 225864 -g HEAD to get the ANGLE/ChangeLog edits

It's really an issue with arrays of any arity?
(got the crash/assert with other numbers, too).

> Source/ThirdParty/ANGLE/src/libANGLE/renderer/metal/ProgramMtl.mm:1274
>          bool hasDepthSampler = false;

Are these related to the array assert or are these in fact fixing some other bug?

Might want to remove this line
