C ++ / clang分析器内存泄漏？ [英] C++/clang analyzer memory leaks?

问题描述

我想让clang ++告诉我有内存泄漏。我试过扫描构建，但它没有报告。我如何获得llvm / clang来警告我这个问题？

I'm trying to get clang++ to tell me there is a memory leak. I tried scan-build but it reported nothing. How do I get llvm/clang to warn me of this problem?

#include <iostream>

int main() {
        int *a = new int;
        *a = 8;
        std::cout<< a << std::endl;
}

推荐答案

有一些类似于保留段的程序所以对于小对象不需要扩展内存区域，尝试应用1024 * 1024 * 10然后检查结果

Because int is too small, there is something like one "reserved section" for program so for small object no need to extend memory area, try to apply 1024 * 1024 * 10 then check the result
