+# panic safety: double drop may happen within `util::{mutate, mutate2}`
+
+Upon panic in a user-provided function `f`, `fn mutate()` & `fn mutate2` drops twice a same object.
+
+Affected versions of this crate did not guard against double drop while temporarily duplicating an object's ownership with `ptr::read()`.
+
+Dropping a same object can result in memory corruption.
+
+The flaw was corrected in version "0.9.11" by fixing the code to abort upon panic.
