# SliceDeque::drain_filter can double drop an element if the predicate panics
Affected versions of the crate incremented the current index of the drain filter
iterator *before* calling the predicate function `self.pred`.
If the predicate function panics, it is possible for the last element in the
iterator to be dropped twice.
