As of RFC 18, struct layout is undefined. Opting into a C-compatible struct layout is now down with #[repr(C)]. For consistency, specifying a packed layout is now also down with #[repr(packed)]. Both can be specified. To fix errors caused by this, just add #[repr(C)] to the structs, and change #[packed] to #[repr(packed)] Closes #14309 [breaking-change]
