| error: Undefined Behavior: atomic operations cannot be performed on read-only memory |
| many platforms require atomic read-modify-write instructions to be performed on writeable memory, even if the operation fails (and is hence nominally read-only) |
| some platforms implement (some) atomic loads via compare-exchange, which means they do not work on read-only memory; it is possible that we could have an exception permitting this for specific kinds of loads |
| please report an issue at <https://github.com/rust-lang/miri/issues> if this is a problem for you |
