How to detect a memory leak under a Linux operating system

1. Development background: When programming with VC in Windows, we usually need to run the program in debug mode, and the debugger will print out memory information that is allocated on the heap while the program is running, including the code filename, line number, and memory size, when exiting the program. This feature is a built-in mechanism provided by the MFC Framework, encapsulated within its class s

Using Mleaksfinder to detect a project memory leak summary

A few days ago to see open source tools Mleaksfinder, decided to use in the company's projects to try, the effect is very good, the usage is very simple, directly to the project folder dragged to the project can be, depending on the project, I found a lot of memory leaks in the company project Place, in this summary: 1, block with reference to external objects must first __weak, otherwise easy to cause circular references; 2, the object of th

* The VLD (visual leak detector) tool used in VC to detect memory leaks

Flexible and freeCA major feature of the language, but this feature also has some unavoidable side effects, such as memory leakage. As we all know, memory leakage is complicated,ProgramDuring normal operation, you cannot see any exceptions, but it is exposed only when it runs for a long time or when a specific operation is repeated multiple times under a specific condition. Therefore,

VLD (visual leak detector), a tool used in VC to detect memory leaks)

Flexibility and freedom are a major feature of the C language, but this feature also brings unavoidable side effects, such as memory leakage. As we all know, the problem of Memory leakage is complicated.

Steps to detect memory leak (draft)

1. Use _ crtdumpmemoryleaks () to check whether there is memory leak in program. With the help of _ crtdbg_map_alloc, it can output Memory Leak info with file line info for those memory block allocated by malloc (), while it wowould never print file line info for those allo

Detect a memory leak with code on Windows by define _CRTDBG_MAP_ALLOC macros

With the memory leak detection tool in VS, to enable memory leak detection, include the following statement in your program: #define _CRTDBG_MAP_ALLOC #include Their order of precedence cannot be changed. By including Crtdbg.h, the malloc and free functions are mapped to their "Debug" version _malloc_dbg and _free_d

Valgrind: detect memory leak and threading bugs

Valgrind is a GPL 'd System for debugging and profiling Linux programs. with valgrind's tool suite you can automatically detect into memory management and threading bugs, avoiding hours of frustrating bug-hunting, making your programs more stable. you can also perform detailed profiling to help speed up your programs.Why shoshould you use valgrind? Valgrind will save you hours of debugging time. with valg

What is a memory leak? (What is a memory leak?)

What is the memory leak in the program? We have written many programs with the keyword Free (). For example, I am in this post about some of the important operations of the list (Important operations on a Linked list) to delete the entire list of this function, the code snippet is as follows:struct node * deletelist (struct node * head) { struct node * temp; while (Head! = NULL) { =

Memory leak detection in Linux (iv) record the size of the leak

subclass's destructor?Because the premise of polymorphism is virtual function.Under normal circumstances, the destructor of a class should be written as a virtual function, which, if forgotten, could cause a memory leak.(2) A space for an array is applied, but only the space of the first element is releasedclassnewclass[5];delete pA;Not all of these situations can lead to

Visual leak detector, a memory leak detection tool under VC ++

. the only exception is stdafx. H (or any other precompiled header ). a precompiled header, such as stdafx. h, must always be the first header encoded in a source file, so VLD. h must be encoded ded after any precompiled headers.2. if your program contains one or more DLLs that you wowould also like to check for memory leaks, then also include VLD. h in at least one source file from each DLL to be removed ded in l

Explanation: Memory overflow, memory leak, memory out of bounds, buffer overflow, stack overflow

may lead to the eventual exhaustion of the system's memory. So, we call this kind of memory leak as an implicit memory leak. from the point of view of the user's use of the program, the memory

sense, a one-time memory leak is harmless because it does not accumulate, and the implicit memory leak is very harmful because it is more difficult to detect than frequent and accidental memory leaks. Detecting

Memory overflow and memory leak _ memory Overflow

, memory leaks can be categorized into 4 categories: 1. Frequent memory leaks. The code that has a memory leak is executed multiple times, causing a memory leak each time it is executed. 2. Accidental
