请问各位仁兄仁姐，上述情况是什么问题，改怎样修改呢？

像是野指针。

[cut9]

0x00405d4b这个指针指的地止已经作废，比如被delete掉了，或者干脆被别的内存操作给冲掉了。
看起来不是dll的问题。根dll没关系。

你调试源代码,这么来：
1.看看到哪一步出的错误，找出这个指针。比如mypointer
2.既然mypointer指的地方被冲掉了，那么要找出什么时候被谁冲掉的或者delete掉的
3.使用2分法。在mypointer刚被分配开始，到第1步那个位置之间，加上对mypointer
的访问,（比如，mypointer指的是字符串，那么打出来看看指的是字符串对不对）
总能找到在哪儿被谁干掉的.
