Derelict OpenGL basic program does not work but OpenGL does not say anything is wrong?

[Nils Forsman via Digitalmars-d-learn]

void main(){
     DerelictGL3.load();
     //create your sdl context, window hints,
     DerelictGL3.reload();
     //Do other stuff...
}

You got to have a valid context before you call reload. These two 
functions shall be called only once, I have the impression that 
you call them multiple times.
