| error: Undefined Behavior: write access through <TAG> (root of the allocation) at ALLOC[0x0] is forbidden |

| | ^^^^^^ write access through <TAG> (root of the allocation) 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> (root of the allocation) is foreign to the protected tag <TAG> (i.e., it is not a child) |
| = help: this foreign write access would cause the protected tag <TAG> (currently Frozen) to become Disabled |
| = help: protected tags must never be Disabled |
| help: the accessed tag <TAG> was created here |
