I added this around the problem line to catch the problem:

     try{
		SDL_RenderCopy(renderer, texture, &sourceRect, &destRect);	
	} catch{}
	finally {
		writeln( "Error: " , SDL_GetError() );
	}

The program now works from a terminal as expected (!) BUT when 
SDL_RenderCopy is called SDL_GetError() shows an 'error code' (or 
just some address/value as it is different each time).
