I've been trying to port a basic GLFW C++ example to D. The C++

Heh, that's the problem.
Does anyone know why the D version does not work?

I ran into this myself, took me awhile to track it down. I too
took the size of dynamic arrays this way:
https://github.com/workhorsy/d_glfw/blob/master/dlang/source/main.d#L158
https://github.com/workhorsy/d_glfw/blob/master/dlang/source/main.d#L161
That will give you 2 words for a slice or dynamic array, the
length and pointer. What you want is the length of the array
https://github.com/joakim-noah/android/blob/master/samples/Teapot/jni/TeapotRenderer.d#L192
multiplied by the size of the element
https://github.com/joakim-noah/android/blob/master/samples/Teapot/jni/TeapotRenderer.d#L195
Sizeof works for static arrays, but is different for slices:
that's likely your problem.
