// These are 12-byte packed structs on x86/x86-64, but on other architectures are 16-byte.
// This means the `data` member is at offset 4 on x86, but offset 8 on other architectures, corrupting the data.
// The queue data is entirely user-controlled, so we can't rewrite data in any sane fashion.
// This is visible with `node.js` as a hang.
