That ostream object is a pile of overloaded functions on the operator <<
std::basic_ostream::operator<< - cppreference.com[^]

NOTE FROM ABOVE .. I underlined the statement parts:
Quote:
There are no overload for pointers to non-static member, pointers to volatile, or function pointers (other than the ones with signatures accepted by the (10-12) overloads). Attempting to output such objects invokes implicit conversion to bool, and, for any non-null pointer value, the value 1 is printed

I avoid the thing like the plague because you have to know it's behaviour .. so yes a non zero volatile pointer will always print as 1 .. it tells you that.

So the good news is there is nothing wrong with your compiler it is following the c++ standard.
If you don't like it take it up with the c++ standard comittee.

Ostream has other strange (but documented) filter behaviour.
For example with char* pointers it has a special overload expecting it to be a pointer to a null terminated string
cout << (char*)0x41 << endl;    // This will crash and burn .. it expects a null terminated string from a char*
cout << (void*)0x41 << endl;    // This will print fine

You could try putting a void* typecast so it goes thru the void* pointer overload ... like so should work
cout << "result " << (void*)result << '\n';

If you are intending to use ostream you will need to learn it's ins and outs and quirky behaviour.
Anyhow it's not a big issue and rolls around ostream behaviour .. so don't make it more than what it is.

Your pointers are clearly adding properly you were just having a display issue with ostream Smile | :)
In vino veritas
