However, the alignment of `{i,u}64` on a 32-bit target can be smaller than `Atomic{I,U}64`. This can cause unaligned memory accesses and data race. Crates using `fetch_*` methods with `AtomicCell<{i,u}64>` are affected by this issue. 32-bit targets without `Atomic{I,U}64` and 64-bit targets are not affected by this issue. This has been fixed in crossbeam-utils 0.8.7. There are currently no known workarounds."}, {"lang": "es", "value": "crossbeam-utils proporciona at\u00f3micos, primitivas de sincronizaci\u00f3n, hilos de alcance y otras utilidades para la programaci\u00f3n concurrente en Rust. crossbeam-utils versiones anteriores a 0.8.7, asum\u00eda incorrectamente que la alineaci\u00f3n de \"{i,u}64\" era siempre la misma que \"Atomic{I,U}64\".
