    Summary: VecCopy allows misaligned access to elements

    Details: `VecCopy::data` is created as a Vec of u8 but can be used to store and retrieve elements of different types leading to misaligned access. The issue was resolved in v0.5.0 by replacing data being stored by `Vec<u8>` with a custom managed pointer. Elements are now stored and retrieved using types with proper alignment corresponding to original types.
