Here is the code which runs: https://play.golang.org/p/ds3KZspFvE
If you press play, it will work fine and gives an expected output, as soon as you uncomment this part: /* func (u *Result) UnmarshalJSON(b []byte) error { var ts Result err := json.Unmarshal(b, &ts) if err != nil { fmt.Println(err) } return nil } */ which basically does nothing, you will get: https://play.golang.org/p/Y9NTzpwyQy runtime: goroutine stack exceeds 250000000-byte limit fatal error: stack overflow runtime stack: runtime.throw(0x122c5a, 0xe) /usr/local/go/src/runtime/panic.go:605 +0x100 runtime.newstack(0x0, 0x0) /usr/local/go/src/runtime/stack.go:1050 +0x960 runtime.morestack() /usr/local/go/src/runtime/asm_amd64p32.s:378 +0xa0 Anyone knows how to solve it? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
