When an entry is kept to be use later with `heap-delete`, its `index` in the owning heap is automatically updated as the entry sifts up or down. However, if the entry is removed from the heap via either a `heap-pop` or a `heap-delete` operation, its index is not invalidated and the entry can still be used later with `heap-delete` and remove the wrong element from the heap. This patch invalidates entries when they leave the heap by setting their index to `f`, and check the index in `entry>index`. |
