Memory Leak Detection

I made a application in QT4 .There is some memory leak .I am continusly deleting pointers.
Is there any way to check and debug memory leak in application

On linux you can use Valgrind. On windows there are also tools available, but they are often commercial like Memory Validator by SoftwareVerify.

Hi, for Visual Studio you can use Visual Leak Detector. It's small and free although probably not as powerful as valgrind.
