| LL | ptr::write(dest, src); |
| | ^^^^^^^^^^^^^^^^^^^^^ write 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 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 |

| LL | y.set(1); |
| | ^^^^^^^^ |
