  1. Heap overflow in Array.prototype.reverse 

    In Array.prototype.reverse, array length is cached and used in ReverseHelper().
ReverseHelper() could invoke FillFromPrototypes(), which can cause a side-effect on the array,
including changing its length. Therefore, the use of cached array length to calculate segment left index
could result in overflow. Fix by clamping array length at zero.
