    Summary: Data races in conquer-once

    Details: Affected versions of conquer-once implements Sync for its OnceCell type without restricting it to Sendable types. This allows non-Send but Sync types such as MutexGuard to be sent across threads leading to undefined behavior and memory corruption in concurrent programs. The issue was fixed by adding a Send constraint to OnceCell.
