e.js: empty = []; out = []; for (var j=0;j<10;++j) { empty[42]; out.push((1 * (1)) | ""); } print(uneval(out)); ./js -j ~/e.js [1, 1, 1965522873, 9, 16, 25, 36, 49, 64, 81]
Why do I need the "empty[42]" part? That's an artifact of how the fuzzer works, rather than something the fuzzer generated :(

This is a super evil bug. We can't do CSE across in-trace branch labels. Will push with r=me until someone + or - it.
