templated struct with union, inits fail, errors/wrong data

I have a templated Vector struct with a union in it. Init of a global Vector
instance like so:

    immutable up = vec4(0, 1, 0, 0);

won't compile with gdc: 'duplicate union initialization for comps'. Inside a
function, it works however. Init like:

    enum up = vec4(0, 1, 0, 0);

will result in a vector with all values being nan (in both global and local
scope).

I have minimized everything into one file.
