error: Undefined Behavior: read access through <TAG> is forbidden
--> $DIR/outdated_local.rs:LL:CC
|
LL | assert_eq!(unsafe { *y }, 1);
| ^^ read access through <TAG> is forbidden
|
= help: this indicates a potential bug in the program: it performed an invalid operation, but the Tree Borrows rules it violated are still experimental
= help: the accessed tag <TAG> has state Disabled which forbids this child read access
help: the accessed tag <TAG> was created here, in the initial state Frozen
--> $DIR/outdated_local.rs:LL:CC
|
LL | let y: *const i32 = &x;
| ^^
help: the accessed tag <TAG> later transitioned to Disabled due to a foreign write access at offsets [0x0..0x4]
--> $DIR/outdated_local.rs:LL:CC
|
LL | x = 1; // this invalidates y by reactivating the lowermost uniq borrow for this local
| ^^^^^
= help: this transition corresponds to a loss of read permissions
