Summary
Double-free and use-after-free for Hive
Details

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.
