> Perhaps it works if you declare the register variable in file scope.
Huh. I honestly expected that not to compile, but it appears to, and it

There is minor perturbation in the build, but as far as I can see, it's just
slightly different register/instruction scheduling.
Why does being at global scope change the diagnostic?
