SliceDeque::drain_filter can double drop an element if the predicate panics

Details
Package slice-deque
Version 0.3.0
URL gnzlbg/slice_deque#90
Date 2021-02-19

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.

See advisory page for additional details.
