A type has conflicting packed representation hints.
Erroneous code examples:
#[repr(packed, packed(2))] // error!
struct Company(i32);
#[repr(packed(2))] // error!
#[repr(packed)]
struct Company(i32);
You cannot use conflicting packed hints on a same type. If you want to pack a
type to a given size, you should provide a size to packed:
#[repr(packed)] // ok!
struct Company(i32);
