For the array as a whole to be aligned, not only must the

Umm, the ```align array``` solution is flat out wrong, please
ignore it. Most likely a bug in the compiler.
Also, why will the address of the first element of the array

The simple desire to arbitrarily align an array is certainly

The main advantage of the struct is that you can heap

Okay we were overthinking the solution.
Just use a static array

You're good to go!
