error: Undefined Behavior: read access through <TAG> is forbidden
--> $DIR/alias_through_mutation.rs:LL:CC
|
LL | let _val = *target_alias;
| ^^^^^^^^^^^^^ 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> is a child of the conflicting tag <TAG>
= help: the conflicting tag <TAG> has state Disabled which forbids this child read access
help: the accessed tag <TAG> was created here
--> $DIR/alias_through_mutation.rs:LL:CC
|
LL | *x = &mut *(target as *mut _);
| ^^^^^^^^^^^^^^^^^^^^^^^^
help: the conflicting tag <TAG> was created here, in the initial state Reserved
--> $DIR/alias_through_mutation.rs:LL:CC
|
LL | retarget(&mut target_alias, target);
| ^^^^^^
help: the conflicting tag <TAG> later transitioned to Disabled due to a foreign write access at offsets [0x0..0x4]
--> $DIR/alias_through_mutation.rs:LL:CC
|
LL | *target = 13;
| ^^^^^^^^^^^^
= help: this transition corresponds to a loss of read and write permissions
