20.9不维护已经好久了，你把这个日志喂给AI看看是什么原因，尝试用AI修复看看吧

该升级了，差好几个版本了。不要老停留在过去

2026-06-09 12:49 deepin 只有AI才能帮你解决问题，20.9官方都抛弃了，就连23都不管了，建议楼主还是换一个靠谱的AI

直接找对应版本的源码让ai在源码层面修。

2026-06-09 16:47 deepin 原理可能是这样的:
在void DFileSystemModel::fetchMore中设置了QtConcurrent并启动了watcher
QtConcurrent在void DFileSystemModel::updateChildrenOnNewThread中定义,并指向void DFileSystemModel::updateChildren
然后watcher启动,并开始执行void DFileSystemModel::updateChildren.(这里不是主线程)
在第6行const FileSystemNodePointer &node = d->rootNode; //先记住,后面有用
然后在第67行执行了beginInsertRows(createIndex(node, 0), 0, list.count() - 1);
按理来说QtConcurrent是无法执行UI层面的操作的,但是他会emit rowsAboutToBeInserted()
这会使得连接了DFileSystemModel的QListView(具体用了什么不清楚,应该是继承了这个的)更新列表,并且是在主线程更新的
如果主进程刷新比QtConcurrent快,就会使得node所指向的东西在主进程中被释放
如果释放了,node应该会变为一个野指针,不过有QPointer在,node会变为nullptr
然后到下一行是node->setChildrenMap(fileHash); 而这个node是否为nullptr就要看谁更快了
如果为nullptr,那就会断错误
至于修正方法,要么不用多线程,要么把beginInsertRows和endInsertRows移出多线程

不是这里的问题
崩溃指令 lock addl $0x1, (%rdi) 访问的地址 (%rdi) 无效，很可能是某个 QSharedPointer 或 QPointer 指向的对象在另一个线程中被释放
