go - Is it possible to recover from a panic inside a panic? -

it looks it's not possible recover panic inside panic?

func testerror(t *testing.t) {      e := &myerr{p: false}     fmt.println(e.error())  // prints "returned"     panic(e)                // prints "panic: returned"      e1 := &myerr{p: true}     fmt.println(e1.error()) // prints "recovered"     panic(e1)               // prints "panic: panic: paniced                             //              fatal error: panic holding locks                              //              panic during panic" }  type myerr struct {     p bool }  func (m *myerr) error() (out string) {     defer func() {         if r := recover(); r != nil {             out = "recovered"         }     }()     if m.p {         panic("paniced")     }     return "returned" } 

backstory: error error() function uses os.getwd, seems panic when inside panic, i'd handle gracefully.

i think solves problem replace this

panic(e1) 

by this

panic(e1.error())

and question here interesting: why? hard part , don't know exact answer. problem here panicing after deffered functions executed (so when go try print panic error string). correction welcomed if it's not correct!
