| error: Undefined Behavior: read access through <TAG> is forbidden |
| --> $DIR/illegal_write5.rs:LL:CC |

| LL | let _val = *xref; |
| | ^^^^^ 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/illegal_write5.rs:LL:CC |

| LL | let xref = unsafe { &mut *xraw }; |
| | ^^^^^^^^^^ |
| help: the conflicting tag <TAG> was created here, in the initial state Reserved |
| --> $DIR/illegal_write5.rs:LL:CC |
| | |
| LL | let xref = unsafe { &mut *xraw }; |
| | ^^^^^^^^^^ |
| help: the conflicting tag <TAG> later transitioned to Disabled due to a foreign write access at offsets [0x0..0x4] |
| --> $DIR/illegal_write5.rs:LL:CC |
| | |
| LL | unsafe { *xraw = 15 }; |
| | ^^^^^^^^^^ |
| = help: this transition corresponds to a loss of read and write permissions |
