如何使用 MacOS Monterey 12.0.1 泄漏查找 Clion c++ 中内存泄漏的确切代码行？

Question

我正在使用 Clion，我想找到一种方法来查找 Mac M1 上的内存泄漏。尚不支持 Valgrind。

让我们看一下这个存在内存泄漏的简单代码：

// Program with memory leak

#include <cstdlib>

using namespace std;

// function with memory leak
void func_to_show_mem_leak()
{
    int* ptr = new int(5);

    // body

    // return without deallocating ptr
    return;
}

// driver code
int main()
{

    // Call the function
    // to get the memory leak
    func_to_show_mem_leak();

    system("leaks SimpleMemoryLeak");
    return 0;
}

我尝试过使用leaks：

leaks *NameOfProccess*

我得到这个输出：

Process 70526 is not debuggable. Due to security restrictions, leaks can only show or save contents of readonly memory of restricted processes.

有什么方法可以获取malloc所在的确切代码行吗？谢谢！
