我的程序代码如下:
#include <iostream>
int main(int argc, const char *argv[])
{
std::cout << "hello world!\n";
return 0;
}
我使用了标志编译它
-Wpedantic -pedantic-errors -std=c++11 -g -Wall -Wextra
运行Valgrind并看到了一些奇怪的东西,这个简单的程序存在内存泄漏,valgrind --leak-check=full --show-leak-kinds=all
命令的输出如下:
==4492== 72,704 bytes in 1 blocks are still reachable in loss record 1 of 1
==4492== at 0x4C28C20: malloc (vg_replace_malloc.c:296)

我的问题是 - 如何找出发生了什么?
(这是关于IT技术的问题)
