Comment #21 on issue 3087 by [email protected]: ES6:
Array.prototype.slice and friends should use ToLength instead of ToUint32
https://code.google.com/p/v8/issues/detail?id=3087
I don't think you even hit these cases within octane. Since the fast path
(FixedArray, FixedDoubleArray with untouched prototype chains) for most of
the critical array functions are implemented directly in builtins.cc. So
octane (and most of the other bench suites) is probably not the most
representative benchmark.
A little microbench of a tight push() or slice() loop will expose possible
defects more clearly.
