A recently discovered fuzz bug reported a difference in execution result between Wasmtime and v8. The module in question had an exported function which had multiple results, including floats. About a year ago I reported a bug on v8 about functions with multiple results leading to incorrect results, and it was fixed many months back but I don't think that we ever actually pulled in that update. After updating v8 I saw the test failure go away, so this update is being done to fix the fuzz bug test failure I saw.
