c++ - C++/clang 分析器内存泄漏？

Question

我试图让 clang++ 告诉我有内存泄漏。我尝试了 scan-build 但它没有报告任何内容。如何让 llvm/clang 警告我这个问题？

#include <iostream>

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

Answer 1

False-positive pruning usually leads to removing all leaks that originate from main(), since the program will exit anyway. Try analyzing the same code, but in a different function.

Answer 2

因为 int 太小，程序有一个“保留部分”，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
