| LL | let _val = *xref; | |
| | ^^^^^ Undefined Behavior occurred here | |
| | | |
| = 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: see https://github.com/rust-lang/unsafe-code-guidelines/blob/master/wip/tree-borrows.md for further information | |
| = 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 | |

| 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 | |
