CodeLoad: 20689 Looks like garbage accumulates that cannot be freed (not even after benchmark finishes, it seems). Expected: no leak. Admittedly, benchmark score doesn't really suffer from this on v8, as long as enough memory is available. What version of the product are you using? v8 3.28.38, octane 2.0
