| = 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 reborrow (acting as a foreign read access) would cause the protected tag <TAG> (currently Active) to become Disabled |
| = help: protected tags must never be Disabled |
