Badger v4.2.0运行时切片越界错误排查求助

运行基于Badger的进程时触发运行时错误：slice bounds out of range，错误源自Badger内部库，而非业务代码。具体报错栈信息如下：

panic: runtime error: slice bounds out of range [-4169358568:] [recovered]
    panic: runtime error: slice bounds out of range [-4169358568:]

使用版本：

• Badger v4.2.0
• Golang 1.19

已尝试两种Badger初始化方式，均触发相同错误：

自定义配置初始化 #

// func to create a key value db
func NewKeyValueDB(dataDir, name string) (*KeyValueDB, error) {
    opts := badger.DefaultOptions(dataDir + "/" + name)
    opts.InMemory = false
    opts.Compression =  options.None
    opts.NumCompactors = 2
    opts.NumGoroutines = 4
    opts.BlockCacheSize = 0
    db, err := badger.Open(opts)
    if err != nil {
        return nil, err
    }
    return &KeyValueDB{
        DB:      db,
        dataDir: dataDir,
        name:    name,
    }, nil
}

默认配置初始化 #

// func to create a key value db
func NewKeyValueDB(dataDir, name string) (*KeyValueDB, error) {
    opts := badger.DefaultOptions(dataDir + "/" + name)
    db, err := badger.Open(opts)
    if err != nil {
        return nil, err
    }
    return &KeyValueDB{
        DB:      db,
        dataDir: dataDir,
        name:    name,
    }, nil
}

请求协助排查该问题。
