Relations of has many causes panic in armv7 device

[levin-go]

The same code can run normally on my computer (x86 windows) and device (armv7 Linux) without using a one to many relationship. Once a one to many relationship is used, it can run normally on my computer (x86 Windows). But when my device (armv7 Linux ) is running, it will cause a panic.

Basic info

• Objectbox version: objectbox-go v1.8.0
• Objectbox lib version: libobjectbox.so v4.0.1
• Device: x86 Windows and armv7 Linux
• Reproducibility: always

Code

• main.go

package main

import (
	"fmt"
	"github.com/objectbox/objectbox-go/objectbox"
	"objectboxTest/objectboxlib/model"
)

func initObjectBox() *objectbox.ObjectBox {
	objectBox, err := objectbox.NewBuilder().Model(model.ObjectBoxModel()).Directory("./opt").Build()
	if err != nil {
		fmt.Println(err)
		return nil
	}
	return objectBox
}

func main() {
	// load objectbox
	ob := initObjectBox()
	defer ob.Close() // In a server app, you would just keep ob and close on shutdown
	box := model.BoxForTask(ob)
	box2 := model.BoxForWorkers(ob)
	if box == nil || box2 == nil {
		panic("box ini fail")
	}
	worker1 := model.Workers{Name: "Petter", Age: 18}
	worker2 := model.Workers{Name: "Leven", Age: 28}
	workers := []*model.Workers{&worker1, &worker2}
	id, _ := box.Put(&model.Task{
		Text:    "Buy milk",
		Workers: workers,
	})
	tasks, err := box.Get(id) // Read
	if err != nil {
		fmt.Println("read err ", err)
		return
	}
	fmt.Println(tasks)
}
