Indeed, that is exactly what I would expect (from my understanding of the
standard), and, as far as I can tell, that is what clang does. I have not
tested other compilers.

To anyone else is affected by this: a workaround (besides not using typedef for
such array types) is to wrap the atomic element type in a struct.

Thanks!
