+The affected version of `rulinalg` has incorrect lifetime boundary definitions
+for `RowMut::raw_slice` and `RowMut::raw_slice_mut`. They do not conform with
+Rust's borrowing rule and allows the user to create multiple mutable references
+to the same location. This may result in unexpected calculation result and data
+race if both references are used at the same time.
