Probably Memory Leak with sf::RenderWindow

[scorcher24]

Adding this code to my program while using WindowsXP SP3 and Visual Studio 2008 Express results in a memory leak.

Code: [Select]


sf::RenderWindow m_window;


Code: [Select]


Detected memory leaks!
Dumping objects ->
{123} normal block at 0x016A6660, 20 bytes long.

 Data: <Hej > 48 65 6A 01
Object dump complete.


Memory report is achieved with:

Code: [Select]


#if defined (_DEBUG) && defined(_MSC_VER)
            long flag = _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG);
            flag |= _CRTDBG_LEAK_CHECK_DF | _CRTDBG_CHECK_ALWAYS_DF;
            _CrtSetDbgFlag(flag);
#endif /* _MSC_VER && _DEBUG */

I have debugged my own application from begin() to end() and if I remove the sfml-code, there are no more leaks. So I can safely say, that it is coming from sfml.

Weird. The RenderWindow default constructor does nothing, and the constructors of its members (including the base classes ones) do nothing as well (there are only primitive types).

Is it happening with this minimal piece of code?

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow w;
    return 0;
}

Yes, it is happening.

(Sorry, its the German version )
Code:

Code: [Select]



#include <sfml/Graphics.hpp>


int main()
{
#if defined (_DEBUG) && defined(_MSC_VER)
            long flag = _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG);
            flag |= _CRTDBG_LEAK_CHECK_DF | _CRTDBG_CHECK_ALWAYS_DF;
            _CrtSetDbgFlag(flag);
#endif /* _MSC_VER && _DEBUG */
    sf::RenderWindow window;
return 0;
}



There are 2 Things which is remarkable:
* It is ALWAYS the same amount of memory which is leaking.
* With 216 Byte in the second chunk it is quite large... more than a "common" class needs normally. Much more.
What version of Visual Studio was this SDK linked against? Perhaps that is the problem. The binaries are marked with VC8, I am using VC9. Could this produce this problem?
Edit: I was wrong, the folder is called "VC2008". So this should be ok.
So long.

Ok, I'll try this piece of code at home. Thanks for your help

[Laurent]

I've tried the exact same code under VS2005, using the latest sources, and everything's fine.
