When experimenting with 9 code, I accidentally generated a corrupt NativeDataView that didn’t contain an ArrayBuffer, something that should be impossible given that the buffer field is constant and assigned at instantiation time only, and checks are done at instantiation time, Hence this is noreg-trivial. I can’t recreate the state in working code.

It can be easily hand verified.
