谁能帮我解决这个问题

推荐答案

Exception code c0000005 是访问冲突的代码.这意味着您的程序正在访问(读取或写入)它无权访问的内存地址.最常见的原因是:

Exception code c0000005 is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:

• 访问过时的指针.那就是访问已经释放的内存.请注意，这种陈旧的指针访问并不总是会导致访问冲突.只有当内存管理器将内存返回给系统时，您才会遇到访问冲突.
• 读取数组的末尾.这是当您有一个长度为 N 的数组并且您访问索引为 >=N 的元素时.

• Accessing a stale pointer. That is accessing memory that has already been deallocated. Note that such stale pointer accesses do not always result in access violations. Only if the memory manager has returned the memory to the system do you get an access violation.
• Reading off the end of an array. This is when you have an array of length N and you access elements with index >=N.

要解决此问题，您需要进行一些调试.如果您无法在开发机器上的调试器下发生故障，您应该获得故障转储文件并将其加载到您的调试器中.这将允许您查看问题发生在代码中的哪个位置，并有望引导您找到解决方案.您需要拥有与可执行文件关联的调试符号才能查看有意义的堆栈跟踪.

To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.
