error: Undefined Behavior: read access through <TAG> is forbidden
--> $DIR/error-range.rs:LL:CC
|
LL | rmut[5] += 1;
| ^^^^^^^^^^^^ read 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 a child of the conflicting tag <TAG>
= help: the conflicting tag <TAG> has state Disabled which forbids child read accesses
help: the accessed tag <TAG> was created here
--> $DIR/error-range.rs:LL:CC
|
LL | let rmut = &mut *addr_of_mut!(data[0..6]);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
help: the conflicting tag <TAG> was created here, in the initial state Reserved
--> $DIR/error-range.rs:LL:CC
|
LL | let rmut = &mut *addr_of_mut!(data[0..6]);
| ^^^^
help: the conflicting tag <TAG> then transitioned from Reserved to Active due to a child write access at offsets [0x5..0x6]
--> $DIR/error-range.rs:LL:CC
|
LL | rmut[5] += 1;
| ^^^^^^^^^^^^
= help: this corresponds to an activation
help: the conflicting tag <TAG> then transitioned from Active to Frozen due to a foreign read access at offsets [0x5..0x6]
--> $DIR/error-range.rs:LL:CC
|
LL | let _v = data[5];
| ^^^^^^^
= help: this corresponds to a loss of write permissions
help: the conflicting tag <TAG> then transitioned from Frozen to Disabled due to a foreign write access at offsets [0x5..0x6]

LL | data[5] = 1;

= help: this corresponds to a loss of read permissions
= note: BACKTRACE (of the first span):
