The const qualification was so far performed before the promotion and the implementation assumed that it will never encounter a promoted. With `const_precise_live_drops` feature, checking for live drops is delayed until after drop elaboration, which in turn runs after promotion. so the assumption is no longer true. When evaluating `NeedsNonConstDrop` it is now possible to encounter promoteds. Use type base qualification for the promoted. It is a sound approximation in general, and in the specific case of promoteds and `NeedsNonConstDrop` it is precise. |
