visual studio - C++ - Memory leak testing with _CrtDumpMemoryLeaks() - Does not output line numbers

Question

I'm working on a game with SDL in Visual Studio 2010. I came across the _CrtDumpMemoryLeaks() macro and thought I'd give it a go. Invoking _CrtDumpMemoryLeaks() does print memory leaks to the output window, but it does not show where it happens.

I've read the MSDN article at Memory Leak Detection Enabling , and it explains that if I define _CRTDBG_MAP_ALLOC it should output the line number of the offending statement. This does not happen in my case. (I was however able to get it to work if I use malloc() directly -- not by using 'new').

The code:

#define _CRTDBG_MAP_ALLOC
#include <crtdbg.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
    int *var = new int(5);

    _CrtDumpMemoryLeaks();

    return 0;
}

The output is the following: Detected memory leaks! Dumping objects -> {58} normal block at 0x007D1510, 4 bytes long. Data: < > 05 00 00 00 Object dump complete.

If _CrtDumpMemoryLeaks() is unable to output line numbers when allocating using 'new' then suggestions for other ways to achieve similar behavior is appreciated.

That's an old version of Visual Leak Detector.
