+description = """
+If an iterator passed to `SmallVec::insert_many` panicked in `Iterator::next`,
+destructors were run during unwinding while the vector was in an inconsistent
+state, possibly causing a double free (a destructor running on two copies of
+the same value).
+
+This is fixed in smallvec 0.6.3 by ensuring that the vector's length is not
+updated to include moved items until they have been removed from their
+original positions.  Items may now be leaked if `Iterator::next` panics, but
+they will not be dropped more than once.
+
+Thank you to @Vurich for reporting this bug.
