SDL2: IMG_Load() - Segmentation fault on Raspberry Pi

Question

This simple code that perfectly works on Ubuntu crashes with a segmentation fault on my Raspberry Pi v3:

#include "SDL2/SDL.h"
#include "SDL2/SDL_image.h"

int main()
{
    char* artworkPath = "./testfile.png";

    if (SDL_InitSubSystem(SDL_INIT_VIDEO) < 0)
    {
        SDL_Log("SDL fails to initialize video subsystem!\n%s", SDL_GetError());
        return -1;
    }
    else
        printf("SDL correctly initialized!\n");

    if((IMG_Init(IMG_INIT_PNG)&IMG_INIT_PNG) != IMG_INIT_PNG)
        printf("IMG_Init: %s\n", IMG_GetError());
    else
        printf("Fine!\n");

    SDL_Surface* artworkSurface = IMG_Load(artworkPath);

    if (artworkSurface == NULL)
    {
        printf("Error on loading PNG image\n");
        return -1;
    }
    else
        return 0;
}

Error on loading PNG image is never shown because it crashes during loading with a segmentation fault, any idea?

SOLUTION

There are bugs on libpng 1.2.50 and 1.6.36 that prevent to correctly load the image.

SDL Image library installs its own dependencies of such library, the correct/only way to use SDL Image on Raspberry Pi is to compile libpng and SDL library from source.

So, download libpng16 (from GitHub) and SDL2_image-2.0.5 (from official site) source code, compile (libpng as first) and install them. In this way you'll find on your system libpng 1.6.38.git that doesn't have this problem
