Summary: Memory leaks in SDL2 (Video)
Product: SDL Reporter: 0.0.0.0
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED DUPLICATE QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: icculus
Version: 2.0.0   
Hardware: x86_64   
OS: Linux   

Description 0.0.0.0 2013-12-14 11:14:54 UTC 
Valgrind shows many bugs in my game after it's closed, but to narrow the search space I just created a simple test program to show the problem from the beginning.

I use Debian Testing, the SDL2 version is here (currently 2.0.0+dfsg1-3): 
http://packages.qa.debian.org/libs/libsdl2.html


This is the program:
//==================================
#include <SDL2/SDL.h>

int main ( int argc, char **argv )
{
    SDL_Init ( 0 );
    SDL_InitSubSystem ( SDL_INIT_VIDEO );is
    SDL_QuitSubSystem ( SDL_INIT_VIDEO );
    SDL_Quit();
}
//==================================


Then I run: "valgrind --leak-check=full filename"
The output is:
==7832== HEAP SUMMARY:
==7832==     in use at exit: 49,973 bytes in 468 blocks

Actually, this is possible a duplicate of bug #2086:
https://bugzilla.libsdl.org/show_bug.cgi?id=2086
Comment 2 0.0.0.0 2013-12-14 11:29:28 UTC 
To be honest, Valgrind shows more the 3500 bugs and I don't know where to start with it. Shall I attach a file with the log? There is a small number of my own bugs but it's impossible to browse through such a big list of leaks.
Comment 3 0.0.0.0 2013-12-14 11:54:12 UTC 
OK, the rest of leaks is my fault (not destroyed window and renderer) so please consider only my first post.
Sorry

Yeah, this is the same issue. Thanks for reporting it, though!
