[严重] xfmt对某些结构体必现OOM

[gogokit]

对于下面的代码xfmt必现OOM

package main

import (
	"github.com/mix-go/xfmt"
)

func main() {
	type MyStruct struct {
		slice []MyStruct
		str   string
	}

	var s MyStruct
	for i := 1; i <= 10; i++ {
		s.slice = append(s.slice, MyStruct{})
	}

	slice2 := s.slice
	slice2 = append(slice2, MyStruct{str: ""})

	s.slice[0].slice = slice2
	xfmt.Println(s.slice)
}

异常信息：

runtime: goroutine stack exceeds 1000000000-byte limit
runtime: sp=0xc0200e0348 stack=[0xc0200e0000, 0xc0400e0000]
fatal error: stack overflow

@58kg 套娃交叉引用导致，你可以用 xfmt:"-" 忽略这个字段
