3. 提供解决heap-buffer-overflow错误的一般步骤 使用AddressSanitizer(ASan):编译时添加-fsanitize=address选项,ASan会在程序运行时检测内存访问错误,并提供详细的错误报告。 分析错误报告:查看ASan输出的错误报告,确定错误发生的具体位置(如文件名、行号)和原因。 审查相关代码:仔细检查引发错误的代码段,
-fsanitize=address 悬空指针(时间问题) Dangling pointer stack-use-after-scope 缓冲区溢出(空间问题) heap-buffer-overflow stack-buffer-overflow global-buffer-overflow stack-use-after-return 默认不使能,需要修改ASAN_OPTIONS=detect_stack_use_after_return=true进行使能 stack-use-after-scope double free 影子...

A heap-buffer-overflow error was detected by AddressSanitizer in thenanomqMQTT codec module. Specifically, theread_bytefunction attempted to access memory address, which lies just beyond the bounds of an allocated 387-byte buffer. Expected behavior Theread_bytefunction is expected to check the bound...

栈:在Windows下,栈是向低地址扩展的数据结构,是一块连续的内存的区域。这句话的意思是栈顶的地址和栈的最大容量是系统预先规定好的,在WINDOWS下,栈的大小是2M(也有的说是1M,总之是一个编译时就确定的常数),如果申请的空间超过栈的剩余空间时,将提示overflow。因此,能从栈获得的空间较小。
