求高手解決list remove崩潰問題

今天循壞跑程序，出現(xiàn)這個錯誤，求高手解答錯誤是怎么引起的？

就給這點(diǎn)信息讓猜原因么？我猜線程安全問題

回復(fù) 2# hellioncu

求高手解答，出現(xiàn)這種錯誤，直接原因，是因?yàn)閘ist 里指針改變了嗎

你這個錯就是指針失效了，指向無效的內(nèi)存地址，還去訪問就錯了

我猜是哪個成員變量保存了迭代器地址，之后其他函數(shù)調(diào)用變動過迭代器沒有通知修改變量，然后把失效的迭代器拿來操作。

迭代器失效吧  我之前也出現(xiàn)這種原因 是因?yàn)槎嗑�程操作同一個list 鎖沒有加好導(dǎo)致的
