Not sure. I've noticed we have this patch in downstream (but there's no proper explanation). If the array is uninitialized at some stage, then this is a false positive. Likely, the static analyzer we have complains that we use the uninitialized array in an expression (in `ArrayRef` ctor), perhaps it is actually filled-in through an `ArrayRef` later, but this is probably too much for the tooling.
