大小为8的Valgrind无效写入 、、 我正在试验C结构,我已经想出了一个后面跟着来自valgrind的invalid read of size 8消息的invalid write of size 8。我的代码只是循环通过参数(如果为argc > 1),并且对于每个文件名,它扫描指示名称和年龄的string和unsigned int (结构播放器)。argv[]){

malloc/free: in use at exit:内存在退出前没有释放 invalid write of size:非法写入内存,一般为数组越界 invalid read of size:非法读内存:一般为数组越界 definitely lost /possibly lost /still reachable in loss record:内存未释放 definitely:确认丢失。程序中存在内存泄露,应尽快修复。 indirectly:间接丢失。...

Invalid write of size 4:表示发现一个错误,这里显示源代码第6行有错误,这里很明显是越界了,所以显示invalid write错误 40 bytes in 1 blocks are definitely lost in loss record 1 of 1:内存泄露错误,泄漏的大小是10* sizeof(int)40byte。 LEAK summary也会显示内存泄漏的情况 ...
