Heap-buffer-overflow错误,即堆缓冲区溢出错误,是一种内存访问错误,发生在程序试图写入堆上分配的内存区域之外的地址时。这种错误通常是由于数组或缓冲区越界访问引起的,可能导致未定义行为,包括程序崩溃、数据损坏或安全漏洞。 2. 分析导致heap-buffer-overflow的常见原因 数组越界:程序访问数组时,索引超出了数组的合法...
Dear Maintainer, We have identified a Heap-buffer-overflow memory bug in sndfile.c in commit c81375f070f3c676496 To reproduce the bug: compile with asan: export CFLAGS="-fsanitize=address -fno-omit-frame-pointer -g" export CXXFLAGS="-fsa...

当我编译时没有标志,我只得到两个空行。用-fsanitize=address编译,我知道heap-buffer-overflow发生在printf行(“%s\n”,buf); 但我不知道为什么会这样。我试着把它修好,但没用。有人能检查一下这个吗? 本站已为你智能检索到如下内容,以供参考:

堆区(heap) 1. 堆区的内存由自己手动分配手动释放的, 如果在使用完后没有及时释放在程序运行完后将由操作系统自动回收, 堆区的内存地址通常是不连续的, 每个堆区都有一个固定8bytes长度的头部标识信息, 且由于内存对齐制度,后面的块长度如果不足8字节则补空对齐。

求助大佬heap-b..最近在力扣上刷数组,总是碰到这个报错,查看csdn之后总结是数组越界,但是这个明明又没有越界,请求大佬给个方向
