Env

go version go1.16.5 darwin/arm64

Step to reproduce

Just run the code:

package main

import (
	"encoding/json"

	gojson "github.com/goccy/go-json"
)

type MyStruct struct {
	Foo *Foo `json:"foo,omitempty"`
}

type Foo struct {
	A []string `json:"a"`
	B int      `json:"b"`
}

func main() {
	s := MyStruct{
		Foo: &Foo{
			A: []string{"ls -lah"},
			B: 0,
		},
	}

	// encoding/json: Work fine
	_, err := json.Marshal(s)
	if err != nil {
		panic(err)
	}

	// go-json: Panic with SIGSEGV!!!
	_, _ = gojson.Marshal(s)
}
