疑似BUG一处, 神TM的索引超出范围

如下函数 ```go func (this *GenPic) ShowPicMini() { for i := 0; i < 4; i++ { for y := 0; y < len(this.picMiniBox[i][0]); y++ { for x := 0; x < len(this.picMiniBox[i]); x++ { fmt.Println("|", i, x, y, len(this.picMiniBox), len(this.picMiniBox[i]), len(this.picMiniBox[i][0])) if this.picMiniBox[i][x][y] == 0 { //这里报错 fmt.Printf("0") } else { fmt.Printf("1") } } fmt.Printf("\n") } fmt.Printf("\n") } } ``` 已下是输出信息 ``` 0| 0 26 0 4 40 40 0| 0 27 0 4 40 40 0| 0 28 0 4 40 40 0| 0 29 0 4 40 40 0| 0 30 0 4 40 40 0| 0 31 0 4 40 40 0| 0 32 0 4 40 40 0| 0 33 0 4 40 40 panic: runtime error: index out of range ```
