Sorry, I posted this comment in the wrong place by accident, so it might be confusing things a little. I actually was referring to the switch a bit above, not specifically the error message. In other words, showing that if `ShAddrAlign: 4` is specified but `AddressAlign: 8` is specified, the 8 is used for padding purposes. In other words, catching the problem I pointed out earlier and that got changed.
