Solidity does not cause any compile errors for this code although the storage variable data is declared with no reference to actually storage (initially)
contract Test { struct Data { uint256 first; uint256 second; } address public someAddress = 0x04068DA6C83AFCFA0e13ba15A6696662335D5B75; mapping(address => Data) public datas; constructor() {} function test(address[] memory users) external view { Data storage data; for (uint256 i = 0; i < users.length; i++) { if (users[i] == someAddress) { data = datas[someAddress]; break; } } } }
Can such declaration cause any problems?
