error: Undefined Behavior: read access through <TAG> at ALLOC[0x0] is forbidden
--> tests/fail/both_borrows/illegal_write5.rs:LL:CC
|
LL | let _val = *xref;
| ^^^^^ read access through <TAG> at ALLOC[0x0] 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 Reserved
--> tests/fail/both_borrows/illegal_write5.rs:LL:CC
|
LL | let xref = unsafe { &mut *xraw };
| ^^^^^^^^^^
help: the accessed tag <TAG> later transitioned to Disabled due to a foreign write access at offsets [0x0..0x4]
--> tests/fail/both_borrows/illegal_write5.rs:LL:CC
|
LL | unsafe { *xraw = 15 };
| ^^^^^^^^^^
= help: this transition corresponds to a loss of read and write permissions
