Historic buggy implementation of ORIGIN opcode.

[andelf]

        case ORIGIN: {
          DataWord originAddress = program.getOriginAddress();

          if (VMConfig.allowMultiSign()) { //allowMultiSign proposal
            originAddress = new DataWord(originAddress.getLast20Bytes());
          }

          if (logger.isDebugEnabled()) {
            hint = ADDRESS_LOG + Hex.toHexString(originAddress.getLast20Bytes());
          }

          program.stackPush(originAddress);
          program.step();
        }

Fails on:

modifier isHuman() {
        address _addr = msg.sender;
        require (_addr == tx.origin, "Human only");

        uint256 _codeLength;
        assembly { _codeLength := extcodesize(_addr) }
        require(_codeLength == 0, "Human only");
        _;
    }
