Derelict3 SDL2 and OpenGL weird SIGSEGV on DerelictGL.reload ()

Trying to install from SDL and OpenGL to D. In particular, SDL2 and OpenGL 3.3 with kernel / forwarding support. (although I left the last two in the example, because it breaks in the same place, regardless of whether they are there). In GLFW, this is equivalent to the following: I seem to screw things up on the SDL end, or the SDL does some magic things that break Derelict - which seems hard to believe, given that Derelict-gl doesn't do all that much except loading a few function pointers, but something goes wrong, and I do not rule out an error in Derelict or SDL, although this is more likely my code.

I do not see this, and here it is:

import std.stdio;
import std.c.stdlib;
import derelict.sdl2.sdl;
import derelict.opengl3.gl;

void fatal_error_if(Cond,Args...)(Cond cond, string format, Args args) {
    if(!!cond) {
        stderr.writefln(format,args);
        exit(1);
    }
}

void main()
{ 
    //set up D bindings to SDL and OpenGL 1.1
    DerelictGL.load();
    DerelictSDL2.load();
    fatal_error_if(SDL_Init(SDL_INIT_VIDEO),"Failed to initialize sdl!");

    // we want OpenGL 3.3
    SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION,3);
    SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION,3);

    auto window = SDL_CreateWindow(
            "An SDL2 window",
            SDL_WINDOWPOS_UNDEFINED,
            SDL_WINDOWPOS_UNDEFINED,
            800,
            600,
            SDL_WINDOW_OPENGL); // we want this window to support OpenGL
    fatal_error_if(window is null,"Failed to create SDL window!");

    auto glprof = SDL_GL_CreateContext(window); // Create the actual context and make it current
    fatal_error_if(glprof is null,"Failed to create GL context!");

    DerelictGL.reload(); //<-- BOOM SIGSEGV

    // just some stuff so we actually see something if nothing exploded
    glClearColor(1,0,0,0);
    glClear(GL_COLOR_BUFFER_BIT);
    SDL_GL_SwapWindow(window);
    SDL_Delay(5000);
    SDL_DestroyWindow(window);
    SDL_Quit();
    writeln("If we got to this point everything went alright...");
}

Like the title of the question, it breaks down into DerelictGL.reload () (which should load OpenGL functions like GLEW). Here stacktrace ...
