Type findfuncbucket shown from gdb

[Yuwei Ba]

Hey guys, sorry for bothering :D

Here I want to ask a small question about the Golang binary debug info.

The steps to reproduce my problem:

1. $ cat symtab.go

```

package main

import (

"fmt"

"net/http"

_ "net/http/pprof"

"os"

)

func main() {

fmt.Println(os.Getpid())

http.ListenAndServe(":9990", nil)

}

```

2. $ go build symtab.go

3. $ ./main`

4. $ gdb -pid $THE-PID

5. (gdb) i types findfuncbucket

All types matching regular expression "findfuncbucket":

Here I wonder the type `findfuncbucket` was defined in https://github.com/golang/go/blob/ff90f4af66c30a819532fda8754bf29e8ae6140e/src/runtime/symtab.go#L498. So I guess it should show up here like

```

(gdb) i types runtime.bucket

All types matching regular expression "runtime.bucket":

File go:

struct runtime.bucket;

typedef runtime.bucketType;

struct struct { F uintptr; p unsafe.Pointer; b *runtime.bucket };

```

would show the type `runtime.bucket` defined in https://github.com/golang/go/blob/ff90f4af66c30a819532fda8754bf29e8ae6140e/src/runtime/mprof.go#L48

So what did I miss here? :D

Thanks!
