推荐答案

如果您向我们显示代码。然而，错误是清楚的。代码释放没有或不再有效的内存。这意味着地址是错误的，因为例如在原始指针上进行指针运算。或者指针已经被释放（双自由）。

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 The code frees memory that is not or no longer valid.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).
