memory leak detecting in C++ with/without Visual L

Question

I want to detect memory leaks of my C++ program in Windows. I read the documentation also on MSDN about mermoy leak detection and I also started using Visual Leak Detector.

I have a doubt about the reporting of the leaks. I am expecting a file name with a line number, but I am always reported the text below. It has all the component of a leak description ( block type, memory address, data, etc..) except for the file name and the line number.

If it is a real leak? If yes do you know why the file/line are not reported? In the meantime I am having a look also at this url

Thanks

Answer 1

If the allocation numbers (the ones in the curled braces) are always the same, this could help. Basically, it described how to make VC++ generate a breakpoint when the allocation with the specified number is attempted.
