Sorry for my English, but I'm Belgian.

I thinks had discover a little memory leak with the SDL_Init() function. I run on Ubuntu 7.04 and i develops a game with SDL libraries and C language.

These following lines are the return of valgrind:
==9420== Address 0x47DD056 is 14 bytes inside a block of size 16,384 alloc'd

My very simplified C code:
#include <SDL/SDL.h>

int main (){
atexit(SDL_Quit);

if ((SDL_Init(SDL_INIT_VIDEO)) == -1){ //line 5
fprintf(stderr,"Error at SDL_Init : %s\n",SDL_GetError());
return -1;
}

SDL_Quit();
return 0;
}

This leak could be inside Xlib...it doesn't happen here with your test program and Valgrind.

However, I could see an unlikely case where SDL_Init() fails that might leak in that sort of way, and I've committed a patch for it in svn revision # 3075 for the 1.2 branch (this patch doesn't apply to the 1.3 branch).
