2020-10-28：go中，好几个go程，其中一个go程panic，会产生什么问题？

package main

import (
    "fmt"
    "time"
)

func main() {
    defer func() {
        recover()
    }()
    defer func() {
        fmt.Println("defer main")
    }()
    go func() {
        fmt.Println("goroutine 1 start")
        defer func() {
            fmt.Println("defer 1")
        }()
        panic("panic1")
        fmt.Println("goroutine 1 end")

    }()
    go func() {
        fmt.Println("goroutine 2 start")
        defer func() {
            fmt.Println("defer 2")
        }()
        time.Sleep(1)
        fmt.Println("goroutine 2 end")
    }()
    time.Sleep(time.Second * 100)
}
