Aggregate function cause error

[IgorSeryogin]

Aggregate function with specific prefix list cause the error. Interesting thing is that commenting any of subnets makes program work correct.

package main

import (
	"net"

	"github.com/mikioh/ipaddr"
)

func main() {
	subnets := []string{
		"109.233.200.0/22",
		"109.233.204.0/22",
		"109.233.208.0/21",

	var prefixes []ipaddr.Prefix

	for _, v := range subnets {
		_, cidr, _ := net.ParseCIDR(v)
		p := ipaddr.NewPrefix(cidr)
		prefixes = append(prefixes, *p)
	}
	ipaddr.Aggregate(prefixes)
}
