SDL automatically closes window in MinGW when using IMG_Load - c++

Question

So I have been following this set of tutorials to get myself some general knowledge with SDL before going to make a game engine with it. However, once I reached this part of the tutorial, I started having issues.
Whenever I would try to use IMG_Load or any related commands, it would cause the program to instantly close. I was doing just fine when I was using SDL_LoadBMP, but now the problem only started to arise now. Even when I copy the code in the tutorial exactly, it still wants to be disagreeable.
bool init()
{
//Initialization flags
bool success = true;
//Initiralize SDL
if(SDL_Init(SDL_INIT_VIDEO) < 0)
{
printf("SDL failed to initialize! Details: %s\n", SDL_GetError());
success = false;
}
else
{
//Set texture filtering to linear
if( !SDL_SetHint( SDL_HINT_RENDER_SCALE_QUALITY, "1" ) )
{
printf( "Warning: Linear texture filtering not enabled!" );
}
//Create a window
gWindow = SDL_CreateWindow("densipoint", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);
if(gWindow == 0)
{
printf("Window failed to display! Details: %s\n", SDL_GetError());
success = false;
}
else
{
//Create renderer for window
gRenderer = SDL_CreateRenderer(gWindow, -1, SDL_RENDERER_ACCELERATED);
if(gRenderer == 0)
{
printf("Renderer failed to be created! Details: %s\n", SDL_GetError());
success = false;
}
else
{
//Initialize renderer color
SDL_SetRenderDrawColor(gRenderer, 0xff, 0xff, 0xff, 0xff);
//Initialize PNG loading
int imgFlags = IMG_INIT_PNG;
if( !( IMG_Init( imgFlags ) & imgFlags ))
{
printf("SDL_image failed to initialize! Details: %s\n", IMG_GetError());
success = false;
}
}
}
}
return success;
}
Any ideas/advice? I'm using command-line MinGW with the g++ compiler.
EDIT: I have narrowed the problem down to issues with initializing SDL_image.
int imgFlags = IMG_INIT_PNG;
if( !( IMG_Init( imgFlags ) & imgFlags ))
{
printf("SDL_image failed to initialize! Details: %s\n", IMG_GetError());
success = false;
}
