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?

Window / [SOLVED] Very simple window (crashes)

« on: July 14, 2011, 05:17:37 pm »

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.
