| error: Undefined Behavior: write access through <TAG> at ALLOC[0x4] is forbidden |

| | |
| LL | v2[1] = 7; |
| | ^^^^^^^^^ 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 write access |
| help: the accessed tag <TAG> was created here, in the initial state Reserved |
| --> tests/fail/both_borrows/buggy_as_mut_slice.rs:LL:CC |
| | |
| LL | let v2 = safe::as_mut_slice(&v); |
| | ^^^^^^^^^^^^^^^^^^^^^^ |
| help: the accessed tag <TAG> later transitioned to Disabled due to a foreign write access at offsets [0x4..0x8] |
| --> tests/fail/both_borrows/buggy_as_mut_slice.rs:LL:CC |
| | |
| LL | v1[1] = 5; |
| | ^^^^^^^^^ |
| = help: this transition corresponds to a loss of read and write permissions |
