abigen error: Failed to generate ABI binding in Golang

Attached zip is my contract source file written in solidiy, and its abi / bin file generated by solc,

then I run this command to generate ABI binding in Golang

./abigen --abi=Vote.abi --bin=Vote.bin --pkg=contracts --type=vote --out=vote.go

but the experted file vote.go has not been generated, and the console printed this message:

Fatal: Failed to generate ABI binding: 465:76: expected ), found 'range' (and 10 more errors)

// Code generated - DO NOT EDIT.
// This file is a generated binding and any manual changes will be lost.

package contracts

import (
	"math/big"
	"strings"
	"errors"

	ethereum "github.com/ethereum/go-ethereum"
	"github.com/ethereum/go-ethereum/accounts/abi"
	"github.com/ethereum/go-ethereum/accounts/abi/bind"
	"github.com/ethereum/go-ethereum/common"
	"github.com/ethereum/go-ethereum/core/types"
	"github.com/ethereum/go-ethereum/event"
)

// Reference imports to suppress errors if they are not otherwise used.
var (
	_ = errors.New
	_ = big.NewInt
	_ = strings.NewReader
	_ = ethereum.NotFound
	_ = bind.Bind
	_ = common.Big1
	_ = types.BloomLookup
	_ = event.NewSubscription
)
// and more output ......

but it is ok to generate ABI binding in Java with same abi/bin files.

Steps to reproduce the behaviour

extract the attached zip into github.com/go-ethereum/build/bin, and run:

./abigen --abi=Vote.abi --bin=Vote.bin --pkg=contracts --type=vote --out=vote.go

Vote.zip

The contract works on test chain.

ok, this is a bug indeed: you are using range as a parameter name, and go will recognize it as its range keyword. We have to somehow escape that name. In the mean time, you can just change range to e.g. rnge in your ABI file.
