This simple test code is giving me an error 'Error executing 
command run: Program exited with code -11' (or a seg fault if 
executed from a terminal). The problem line is:

SDL_RenderCopy(renderer, texture, &sourceRect, &destRect);

I've tried this call with the 'null' options as well as passing 
the address of the rects but neither works (I've also tried 
manually assigning the various struct components rather than 
using the c style initialisation in case that was the problem).

Any ideas please?

import derelict.sdl2.sdl;
import std.stdio;

void main()
{
    scope(exit) SDL_Quit();

    DerelictSDL2.load();
    writeln( "SDL loaded ok");


    //init sdl
        if (SDL_Init(SDL_INIT_EVERYTHING) != 0){
                writeln("SDL_Init Error: ", SDL_GetError() );
                return;
        }
                
        //open a window
	SDL_Window *window = SDL_CreateWindow("Window Title!", 100, 
100, 640, 480, SDL_WINDOW_SHOWN);
        if (window == null){
                writeln("SDL_CreateWindow Error: ", SDL_GetError() );
                return;
        }       
                
        //get a renderer (ie buffer), use software renderer for now
	SDL_Renderer *renderer = SDL_CreateRenderer(window, -1, 
SDL_RENDERER_SOFTWARE);
        if (renderer == null){
                writeln( "SDL_CreateRenderer Error: " , SDL_GetError() );
                return;
        }
        
        //load a bitmap
        SDL_Surface *image = SDL_LoadBMP("./test.bmp");
        if (image == null){
                writeln( "SDL_LoadBMP error: " , SDL_GetError() );
                return;
        }       
        
        //create texture for bitmap
	SDL_Texture *texture = SDL_CreateTextureFromSurface(renderer, 
image);
        if (texture == null){
		writeln( "CreateTextureFromSurface error: " , SDL_GetError()

                return;

    //copy to renderer at correct position & scale
    SDL_Rect sourceRect = { 0, 0, 64, 64 };
    SDL_Rect destRect = { 100, 100, 64, 64 };
    SDL_RenderCopy(renderer, texture, &sourceRect, &destRect);  
                
        
    //display and pause
    SDL_RenderPresent(renderer);
    SDL_Delay(2000);
        
                
}

I'm running ArchLinux 64-bit on Vbox and tested out the code.
There haven't been any problems. Have you tried updating
whatever tools you're using?(dmd, dub, etc....) Might've been an 
outdated piece of software that's been making the fuss.
