| = 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> 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 Reserved) to become Disabled |
| = help: protected tags must never be Disabled |
