crossbeam-utils provides atomics, synchronization primitives, scoped
threads, and other utilities for concurrent programming in Rust.
crossbeam-utils prior to version 0.8.7 incorrectly assumed that the
alignment of {i,u}64 was always the same as Atomic{I,U}64. 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.

| tyhicks | mozjs contains a copy of the SpiderMonkey JavaScript engine |
| sbeattie | rustc 1.58.1+dfsg1~ubuntu1-0ubuntu1/jammy fixed this in the 0.8.5 embedded code copy, but not the 0.7.2 copy. |
| mdeslaur | librsvg doesn’t appear to use AtomicCell |
