Compiler assertion when specifying alignment on empty struct

[hryx]

I have no experience with alignment yet, so I don't know what's special about this or how to look into it. Apologies if it's a duplicate.

pub fn main() void {
    var s: struct {} align(4) = undefined;
}

Assertion failed. This is a bug in the Zig compiler.

I'm pretty sure 0 sized variables can't have memory representation so it also cannot be aligned.

Makes sense, I figured my example was probably invalid. This can track the compiler bug at least.
