It's definitely a bug in the SDL library. I can reproduce leaks here,
too, if I just compile this simple program with -fsanitize=address and run
it:
#include <stdio.h>
#include <SDL2/SDL.h>
int main()
{
SDL_Init(SDL_INIT_VIDEO);
SDL_Quit();
return 0;
}
Maybe related to https://github.com/libsdl-org/SDL/issues/5759 ... I added
a comment there.
