don't UB on dangling ptr deref, instead check inbounds on projections This implements https://github.com/rust-lang/reference/pull/1387 in Miri. See that PR for what the change is about. Detecting dangling references in `let x = &...;` is now done by validity checking only, so some tests need to have validity checking enabled. There is no longer inherently a "nodangle" check in evaluating the expression `&*ptr` (aside from the aliasing model). r? `@oli-obk` Based on: - https://github.com/rust-lang/reference/pull/1387 - https://github.com/rust-lang/rust/pull/115524 |
