Struct with embedding struct pointer set to nill causes panic

[alex-kostirin]

Consider the following code:

type J1 struct {
    Field1 string `json:"field_1"`
    Field2 string `json:"field_2"`
}

type J2 struct {
    *J1
    Field3 string `json:"field_3"`
    Field4 string `json:"field_4"`
}

func Show() {
    v := J2{
        Field3: "3",
        Field4: "3",
    }
    b, _ := easyjson.Marshal(v)
    println(string(b))
}

Expected behaviour: Print {"field_3":"3","field_4":"3"} on Show call as package json works

Actual behaviour: panic: runtime error: invalid memory address or nil pointer dereference

Panic raises in the following generated code:

func easyjsonBd361432EncodeEasyjsonBug(out *jwriter.Writer, in J2) {
    out.RawByte('{')
    first := true
    _ = first
    {
        const prefix string = ",\"field_3\":"
        out.RawString(prefix[1:])
        out.String(string(in.Field3))
    }
    {
        const prefix string = ",\"field_4\":"
        out.RawString(prefix)
        out.String(string(in.Field4))
    }
    {
        const prefix string = ",\"field_1\":"
        out.RawString(prefix)
        out.String(string(in.Field1))
    }
    {
        const prefix string = ",\"field_2\":"
        out.RawString(prefix)
        out.String(string(in.Field2))
    }
    out.RawByte('}')
}

I see the same error. Is there any solution or workaround for the issue?
