+# panic safety issue in `impl TransformContent<S, D> for [S; (2|3|4)]`
+
+Affected versions of this crate did not guard against double drop while temporarily duplicating objects' ownership using `ptr::read()`. Upon panic in a user-provided function `conversion`, objects that are copied by `ptr::read()` are dropped twice, leading to memory corruption.
+
+The flaw was corrected in v0.9.2 by using `ManuallyDrop<T>` to enclose objects that are to be temporarily duplicated.
