runtime: multiple definition of 'go:itab.runtime.errorString,error'

Go version

go1.23.2

Output of go env in your module/workspace:

Doesn't matter.

What did you do?

I'm trying to customize some of the features in the runtime. However I ran into a problem.

To simplify, here is an example.

Add this function to runtime.

func Demo() error {
    return errorString("hello")
}

main.go

package main

import "C"
import (
    _ "plugin"
    "runtime"
)

func main() {
    err := runtime.Demo()
    println(err)
}

Build using go build main.go.

What did you see happen?

go/pkg/tool/linux_arm64/link: running gcc failed: exit status 1 /usr/bin/ld.gold: error: /tmp/go-link-2461440430/go.o: multiple definition of 'go:itab.runtime.errorString,error' /usr/bin/ld.gold: /tmp/go-link-2461440430/go.o: previous definition here collect2: error: ld returned 1 exit status

What did you expect to see?

Build success

There are two duplicate symbols in go.o: go:itab.runtime.errorString,error, and their attributes are Global.
