I have been trying to get _CrtDumpMemoryLeaks() to report the allocation
point file and line number in my source file. Instead it always reports the
allocation occurred in crtdbg.h, line 692. I would like it to report my
source file name and line number. What am I missing?
Thanks,
Bill Rogers

Test program code:

// LeakTest.cpp : Defines the entry point for the console application.

#define _CRTDBG_MAP_ALLOC

#include <stdlib.h>

#include <crtdbg.h>

#include <tchar.h>

int _tmain(int argc, _TCHAR* argv[])

{

char *s = new char[100];

_CrtDumpMemoryLeaks();

return 0;

}



This produces the following output in the output window:

Detected memory leaks!

Dumping objects ->

c:\program files\microsoft visual studio .net 2003\vc7\include\crtdbg.h(692)
: {43} normal block at 0x00320FF0, 100 bytes long.

Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD

Object dump complete.

The program '[1932] LeakTest.exe: Native' has exited with code 0 (0x0).

This will become more stupid if you are using STL.... The build-in
mechanism is very simple...

If you want a detailed info with the callsatck (so you can see what really
happens), then use the Memory-Leak-Finder:

Do you need a memory-leak finder ?
