There's not really an associated fix for this.  It's more just a defensive
patch: it's trying to make sure that the equivalent of the aarch64 bug
doesn't creep (back) into arm.  It was the same idea in the other direction
for 0f0b00033a71ff728d6fab6f9d: I've no evidence that those tests ever
failed on aarch64, but it seemed like a good idea to add aarch64
equivalents of the failing arm tests.

Thanks,
Richard
