error: Undefined Behavior: deallocation through <TAG> is forbidden
--> RUSTLIB/alloc/src/alloc.rs:LL:CC
|
LL | unsafe { __rust_dealloc(ptr, layout.size(), layout.align()) }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ deallocation 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 allocation of the accessed tag <TAG> also contains the strongly protected tag <TAG>
= help: the strongly protected tag <TAG> disallows deallocations
help: the accessed tag <TAG> was created here
--> $DIR/strongly-protected.rs:LL:CC
|
LL | drop(unsafe { Box::from_raw(raw) });
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
help: the strongly protected tag <TAG> was created here, in the initial state Reserved
--> $DIR/strongly-protected.rs:LL:CC
|
LL | fn inner(x: &mut i32, f: fn(&mut i32)) {
| ^
help: the strongly protected tag <TAG> then transitioned from Reserved to Active due to a child write access at offsets [0x0..0x4]
--> $DIR/strongly-protected.rs:LL:CC
|
LL | drop(unsafe { Box::from_raw(raw) });
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
= help: this corresponds to an activation
