推荐答案
如果您向我们展示了code只能提供精确的解决方案。错误然而很清楚。在code释放内存，是不是或不再有效。这意味着，无论是地址是错误的，因为指针运算的例子原始指针正在做。或指针已被释放（双免费）。
The exact solution can only be provided if you show us the code. The error is however clear. The code frees memory that is not or no longer valid. That means either the address is wrong, because for example of pointer arithmetic being done on the original pointer. Or the pointer has already been freed (double free).
