tools, the following is how to use the above two points for memory leak detection. But to tell the truth, I did not use the very skilled, but in the process of doing the project, groping out a little bit of conversation, let's share here. Later, if there is a new understanding in this respect, later, and then to share
Currently, an application that analyzes real-time traffic is developed in Linux, and a memory leak is found in the program during a joint test.This is anxious, will soon be on-line, fortunately found a valgrind tool, the perfect solution to the problem of memory leaks.Recommend you can use to see.Valgrind is a set of simulation-based program debugging and analysi

The primary tools for detecting memory leaks are the debugger and the C run-time library (CRT) debug heap functions. To enable the debug heap function, include the following statement in your program:#define _crtdbg_map_alloc#include

Helgrind is a thread error detector. It helps to make your multithreaded routines more accurate.
DRD is also a thread error detector. It is similar to Helgrind, but uses different analytical techniques, so it is possible to find different problems.
Massif is a heap analyzer. It helps to make your program use less mem

6) whether it is the release version or the debugging version of the program, the above points can be achieved.
Here, we recommend that you use leakdiag, a tool developed by Microsoft.

Visual Leakdetector (VLD) is a free memory leak detection Tool for Visual C + +. It is characterized by: (1), it is free open source, using the LGPL protocol, (2), it can get the memory leak point of the call stack, you can get the file and line number, (3), it can get the f
matched. Trace the declaration period of each piece of memory, for example: Whenever a piece of memory is requested, the pointer to it is added to the list, when released, then the corresponding pointer is removed from the list, to the end of the program to check the list to know that there is no memory leaks. The Visual Studio debugger and the C runtime (CRT) u
1. Static analysisWith static analysis, we can get the most initial insight into some of the code's non-canonical places or memory leaks, which is our first step in detecting memory leaks. Of course, there are some warnings that we don't care about to skip.2. Check for memory leaks with instrumentsThis method can roughly locate where we have a
class and the active object reserved by the native code (local codes). So GC roots is a sharp tool to analyze why objects still exist in memory.GC Root Tracing algorithm for the determination of recoverable objects
The above passage also writes out the basic idea of detecting memory leaks: Search down as the starting point of the object "GC Roots", where the path is called a reference chain, and when an object to the GC Roots is not connected to any
