# Double-free and use-after-free for Hive
`Drop` implementation for `Hive` did perform free, but so did `Hive::close`, which,
at the end of the scope performed `Drop`, therefore triggering double-free.

Additionally, function `Hive::from_handle` was not marked as unsafe, making it,
in combination with `as_handle` easy to clone and trigger double-free in safe
code or triggering UB when using invalid pointer.
