error: Undefined Behavior: read access through <TAG> is forbidden
--> $DIR/write-during-2phase.rs:LL:CC
|
LL | fn add(&mut self, n: u64) -> u64 {
| ^^^^^^^^^ 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 child read accesses
help: the accessed tag <TAG> was created here, in the initial state Reserved
--> $DIR/write-during-2phase.rs:LL:CC
|
LL | let _res = f.add(unsafe {
| ________________^
LL | | let n = f.0;
LL | | // This is the access at fault, but it's not immediately apparent because
LL | | // the reference that got invalidated is not under a Protector.
LL | | *inner = 42;
LL | | n
LL | | });
| |______^
help: the accessed tag <TAG> then transitioned from Reserved to Disabled due to a foreign write access at offsets [0x0..0x8]
--> $DIR/write-during-2phase.rs:LL:CC
|
LL | *inner = 42;
| ^^^^^^^^^^^
= help: this corresponds to a loss of read and write permissions
