[signal SIGSEGV: segmentation violation code=0x80 addr=0x0 pc=0x7e2fda

[baiyuxiong]

Description

Code here is :

	tx := repo.db(ctx)
	if param.GroupID != 0 {
		tx = tx.Where(" group_id = ?", param.GroupID)
	}
	if param.AuthProductID != "" {
		tx = tx.Where(" product_pkid = ?", param.AuthProductID)
	}
	if param.CodeOrder != "" {
		tx = tx.Where(" code_order = ?", param.CodeOrder)
	}
	tx = tx.Select("group_id,auth_product,product_pkid,count(case when status=2 then status end) as used_num,count(case when status=3 then status end) as expire_num,count(case when status=1 then status end) as idle_num").Group("group_id,auth_product,product_pkid")
	if err = tx.Count(&total).Error; err != nil {
		return
	}
	err = tx.Offset(param.Offset).Limit(param.Limit).Order("group_id DESC").Find(&rows).Error

We got panic below:
