I expect size of Union1 is 5 (5 bytes == char + uint == 5).
Is this my bug or DMD?
`align(1) union Union1` will do the trick.
what you did is members packing. but the union itself is padded to integer
size too. i.e. internal `align` will set aligning for *members*, and
external `align` will change padding of the whole thing.
