Strange segfault (Derelict/OpenGL)

[Robin Schroer via Digitalmars-d-learn]

I'm not entirely sure where to post, so I will put it here.

I'm playing around with D and Derelict 3 to make something with 
OpenGL (don't really know what yet). I managed to open a window, 
add an OpenGL context, clear the screen and flip buffers. But as 
soon as I try to render a triangle, my program crashes. I already 
tried hardcoding values in the shaders to rule them out. I end up 
with:

Error executing command run: Program exited with code -11

Upon running with gdb, I get:

Program received signal SIGSEGV, Segmentation fault.
0x0000000000000000 in ?? ()

which is not really helpful to me.

dub -v's output:

[...]

Full exception:

I am using the current master versions of Derelict, dub 0.9.21, 
dmd v2.066.0, on Linux 3.15.7 x86_64

I can post my source if needed, but it is quite a lot already. 
I'm not really sure if it is my fault or a bug in Derelict or 
dmd, hopefully someone is able to track this down.
