"description": "When storage arrays whose elements occupy more than a single storage slot are directly encoded in function calls or using abi.encode*, their elements are read in an overlapping manner, i.e. the element pointer is not properly advanced between reads. This is not a problem when the storage data is first copied to a memory variable.",
