Double free in containers
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.
