    Summary: Flaw in offset_of and span_of causes SIGILL, drops uninitialized memory of arbitrary type on panic in client code

    Details: Affected versions of this crate caused traps and/or memory unsafety by zero-initializing references. They also could lead to uninitialized memory being dropped if the field for which the offset is requested was behind a deref coercion, and that deref coercion caused a panic. The flaw was corrected by using `MaybeUninit`.
