Using Visual Leak Detector

阅读更多关于 Using Visual Leak Detector

问题 I have C++ code that crashes randomly. In the code I have used some of the Qt libraries. The compiler is MSVS 2010. Based on some suggestions that this could be due to memory leaks, I started looking in this using Visual Leak Detector. I am very new to Visual Leak Detector and memory leak detection. Here is the code in main.cpp: int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); return a.exec(); } And also the MainWindow constructor looks like this:

Programm parallel QThread is creating a memory leak on application quit

问题 I have a bigger project, with a GUI and I want to manage some files in the background. I've implemented a new thread for this task and on runtime, everything works great. But as soon as I quit the application visual-leak-detector finds 3-7 memory leaks. I separated my threading code and created a new project to check this with a minimal code example, but I'm still not able to fix my issue. I think it has something to do with the event loop of the main program. Maybe the loop doesn't process

问题 I'm using visual leak detector. It displays the call stack properly for some leaks, but I get some outputs that the call stack is empty like this: ---------- Block 131148 at 0x69B3AF68: 144 bytes ---------- Leak Hash: 0xCA7D251C, Count: 1, Total 144 bytes Call Stack (TID 1600): Data: B8 0A 80 01 01 00 00 00 7F 7D 00 00 00 00 00 00 ........ .}...... 00 00 00 00 A4 81 1A 00 17 00 00 00 A8 AE EA 4E ........ .......N 40 EE 22 53 00 00 70 42 FB 19 CC BD D4 E7 2E 00 @."S..pB ........

问题 I am a bit new to using Visual Studio 2013 and am trying to get Visual Leak Detector (Version 2.3) working so that I can check my projects for memory leaks. I've got it installed and have added C:\Program Files (x86)\Visual Leak Detector\include to my include directories and C:\Program Files (x86)\Visual Leak Detector\lib\Win32 to my library directories (both for debug mode). I build and run the following simple program using the debug menu (or hitting f5): #include <iostream> #include <vld.h

Visual C++ - Memory Leak Detection

Any suggestions? This SO post talks about Visual Leak Detector , but I'm looking for other tools. Also, please don't recommend this . I've used Visual Leak Detector quite recently and it works pretty well. It's very simple to build it in (just include vld.h ) and doesn't require any instrumentation. I found that I needed to write a couple of scripts though to parse the output into something more useful for my purposes (it is crying out for a decent GUI). Note the new website -- the project is being actively maintained on Codeplex -- the Codeproject link is very old. Try Deleaker or DevPartner
