 Memory leaks are among the most subtle and hard-to-detect bugs in C/C++ apps. Memory leaks result from the failure to correctly deallocate memory that was previously allocated. A small memory leak might not be noticed at first, but over time can cause symptoms ranging from poor performance to crashing when the app runs out of memory. A leaking app that uses up all available memory can cause other apps to crash, creating confusion as to which app is responsible. Even harmless memory leaks might indicate other problems that should be corrected.

 One technique for finding memory leaks begins by placing `_CrtMemCheckpoint` calls at the beginning and end of your app, then using `_CrtMemDifference` to compare the results. If `_CrtMemDifference` shows a memory leak, you can add more `_CrtMemCheckpoint` calls to divide your program using a binary search, until you've isolated the source of the leak.
 
 ## False positives
+
  `_CrtDumpMemoryLeaks` can give false indications of memory leaks if a library marks internal allocations as normal blocks instead of CRT blocks or client blocks. In that case, `_CrtDumpMemoryLeaks` is unable to tell the difference between user allocations and internal library allocations. If the global destructors for the library allocations run after the point where you call `_CrtDumpMemoryLeaks`, every internal library allocation is reported as a memory leak. Versions of the Standard Template Library earlier than Visual Studio .NET may cause `_CrtDumpMemoryLeaks` to report such false positives.
