Question

Detecting Memory Leaks

Asked by: mnezuk

In order to see if my app leaks memory I am calling _CrtDumpMemoryLeaks() when exiting. I then get a list of all memory leaks. However most of the entries in the list point to my CStrings as the guilty ones. But CStrings are supposed to manage their memory themselves. Isn't that right?

Is there a better way to detect memory leaks besides using _CrtDumpMemoryLeaks() or besides overloading the 'new' and 'delete' operators????

Thanks

Depends on your IDE, MS Visual C++ which comes with Visual Studio has a debug mode you can use to detect memory leaks.

Here is a guide from microsoft "Detecting and Isolating Memory Leaks Using Microsoft Visual C++"

I don't want to (and can't) use any _Crt... related memory leak detectors.  _Crt... related functions only deal with malloc and free (as the microsoft site points out). I am using new and delete.

CStrings manage their own *internal* memory but you still have to deallocate the ones that you allocated.
