<pre>I managed to use glslangValidator to debug the issue. The cause was
referencing a non-existent "position" field in struct Ray (the V variable in
those functions). Replacing it with the correct field name, "origin", stopped
it crashing. A different struct Surface has a "position" field of type vec3,
the same type as the "origin" field of struct Ray.</pre>
