tl;dr; What is a proper way to initialize object on stack or on heap?

I want to make a profiling tool that can track time for iterative purposes and for single measurements – so that I can use same object to measure average time for single function (called N times) but also to see how functions behave in complex project.

Now, I might be wrong, but the way I see it this object needs to be able to be initialized with reference (if there is global tracker) and independently on heap ( if its one use). I tried to mangle something that could work as MRE, so please consider this code:

struct test{
    
    test(const char *caller, int l )
    :caller(caller),line(l),pntr(nullptr),flag(0)
    {
        std::clog << "instantiated as heap" << std::endl;
        this->make_heap();
    }
    
    test(const test & other)
    {
        std::clog << "copyingt";
        this->caller = other.caller;
        this->line = other.line;
        if( other.is_as_referenece())
        {
            std::clog << "as referencen";
            this->pntr = other.pntr; // multiple pointers to same variable??
            this->flag = other.flag;
        }
        else
        {
            std::clog << "as heapn";
            this->pntr = new unsigned(*other.pntr);
            this->flag = other.flag;
        }
    }
    
    test( test && other)
    {
        std::clog << "movingt";
        this->caller = other.caller;
        this->line = other.line;
        other.caller = ""; // moved, thus no caller 
        other.line = 0; // moved, thus no line number
        
        if( other.is_as_referenece())
        {

            other.unlink_reference();
        }

        }

#define TESTER_HEAP test temp = test(__FUNCTION__,__LINE__);

Where to gain function call and line (for g++ (C++11.4), Ubuntu) I need a macro to initialize it to correctly place in source. Now with scope testing, valgrind and gdb have no issues:

void test_macro()
{
    unsigned value = 123;    
    
    {
    TESTER_HEAP
    std::cout << temp << std::endl;
    }
    
    std::cout << std::endl;
    
    {
    TESTER_HEAP
    temp = value;
    std::cout << temp << std::endl;
    }
    
    std::cout << std::endl;
    
    {
    TESTER_HEAP;
    test temp2 = temp;
    std::cout << temp << std::endl;    
    std::cout << temp2 << std::endl;
    }
    
    std::cout << std::endl;
    
    {
    TESTER_HEAP;
    test temp2 = (test &&)temp;
    std::cout << temp << std::endl;    
    std::cout << temp2 << std::endl;
    }
}

I tried googling this and it is possible that due to some terminology i simply wasn’t searching for right things since search was unhelpful. I am sure there are plethora of people who are more experienced and smarter than me who had tried something similar. So can kind people of SE help by pointing to right direction or sharing how they approached heap and stack allocation within same object?
