Missing typevar results in japi3 function

When I run the following kernel (taken from a Lattice Boltzmann simulation)

function advance_gpu!(ρ::CuDeviceArray{T,D}, u::CuDeviceArray{SVector{D,T},D},
        δt::T, δx::T, τ::T, e::CuDeviceVector{SVector{D,T}}, w::CuDeviceVector{T}) where {D,Q,T<:AbstractFloat}
    x = (blockIdx().x-1) * blockDim().x + threadIdx().x
    y = (blockIdx().y-1) * blockDim().y + threadIdx().y
    NX, NY = size(u)
    cs = one(T) / sqrt(T(3))
    eq0 = zero(MVector{Q,T})
    # predictor step
    ρ0, u0 = zero(T), zero(SVector{D,T})
    for q ∈ 1 : Q
        i, j = Int(x-δt*e[q][1]), Int(y-δt*e[q][2])
        if     i < 1    i = NX
        elseif i > NX   i = 1   end
        if     j < 1    j = NY
        elseif j > NY   j = 1   end
        uij = u[i,j]
        uu = dot(uij, uij)
        eu = dot(e[q], uij)
        eq0[q] = ρ[i,j] * w[q] * ( one(T) + eu/cs^2 + 0.5*(eu^2 - cs*uu)/cs^4 )
        ρ0 += eq0[q]
        u0 += eq0[q] * e[q]
    end
    u0 = u0 / ρ0

    # corrector step
    ρ[x,y] = ρ0
    sumneq = zero(T)
    uu = dot(u0, u0)
    for q ∈ 1 : Q
        eu = dot(e[q], u0)
        eq1 = ρ0 * w[q] * ( one(T) + eu/cs^2 + 0.5*(eu^2 - cs*uu)/cs^4 )
        sumneq += e[q] * (eq1 - eq0[q])
    end
    u[x,y] = u0 - (one(T) - one(T)/τ) * sumneq / ρ0
    nothing
end

I get the following error:

I'm not sure how to proceed with debugging this and was advised to post an issue here. The entire code, including a working CPU fallback, initialization and a wrapper for the GPU kernel is available in the following gist: https://gist.github.com/dextorious/e0a1d03a4fdfd29dc6cb5d58d84c53c1

Just running the file should automatically trigger the error.
