Window / memory leaks in sf::window?

« on: July 15, 2011, 12:22:51 am »

I'm using 1.6 and I re-compiled it through VS2010.

The leaks aren't the same as the one in that old thread (it's actually significantly larger), but according to your old post you're saying that it could just be that at the time of the reporting the memory wasn't freed yet but eventually is?

Window / memory leaks in sf::window?

« on: July 14, 2011, 11:23:45 pm »

I re-compiled sfml-system and sfml-window through VS2010

simple test program

Code: [Select]


//////// Used to check memory leaks
    #include <stdlib.h>
    #include "LeakCheck.h"
    #undef THIS_FILE
    static char THIS_FILE[] = __FILE__;

#include <SFML/Window.hpp>

#pragma comment( lib, "sfml-system-d" )
#pragma comment( lib, "sfml-window-d" )

int main()
{
    #ifdef _DEBUG
        _CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
        _CrtDumpMemoryLeaks();
    #endif

    sf::Window App;

    return 0;
}


and here is my output :

Code: [Select]

What's going on? I'm looking at the source for sf::Window() and it's an empty constructor, so what could be causing this so-called memory leak?

Thank you. That did the trick.

I linked to the system library and I still get the same crash.

Release mode :

Code: [Select]


#include <SFML/Window.hpp>

#pragma comment( lib, "sfml-system" )
#pragma comment( lib, "sfml-window" )

int main()
{
    sf::Window App1( sf::VideoMode(800, 600, 32), "Window 1" );
    App1.Close();
    return 0;
}


The reason why I linked both versions is because if I link just the debug libraries

Code: [Select]


// debug mode

#include <SFML/Window.hpp>

#pragma comment( lib, "sfml-system-d" )
#pragma comment( lib, "sfml-window-d" )

int main()
{
    sf::Window App1( sf::VideoMode(800, 600, 32), "Window 1" );
    App1.Close();
    return 0;
}


I get "The application was unable to start correctly (0xc0150002). Click OK to close the application."

However, if I link both versions

Code: [Select]


// debug mode

#include <SFML/Window.hpp>

#pragma comment( lib, "sfml-system" )
#pragma comment( lib, "sfml-system-d" )
#pragma comment( lib, "sfml-window" )
#pragma comment( lib, "sfml-window-d" )

int main()
{
    sf::Window App1( sf::VideoMode(800, 600, 32), "Window 1" );
    App1.Close();
    return 0;
}


I don't get THAT error BUT it still crashes with the message in the original post.

Also all of the dlls are in the executable directory.

I'm using the 1.6 version and VS2010.

Code: [Select]

#include <SFML/Window.hpp>

#pragma comment( lib, "sfml-window" )
#pragma comment( lib, "sfml-window-d" )

int main()
{
    sf::Window App1( sf::VideoMode(800, 600, 32), "Window 1" );
    App1.Close();
    return 0;
}

It crashes at exit of main() (at } ). It says "Run-Time Check Failure #2 - Stack around the variable 'App1' was corrupted."

It happens with both debug and release build.
