I have a C++ windows application which has some memory leak issues. Is it possible to analyze the memory leak from the dump using NTSD ? If so please guide me how to do that ?
I have also heard that we can do it using User Mode Dump. I am not very familiar with finding leaks in windows. It is very easy in Linux with Valgrind.
Is there any other better options to check this ?
see here for details about Visual Leak Detector. I have used it on Windows. all you do in your application is to
#include <vld.h>
and you will see a report about detected leaks in terminal when debugging your program, something like this:

I've had great success tracking down memory and resource leaks with DrMemory . It works with both GCC and MSVC and it's very straight forward to use.
