vcat Error

[DavidBegert]

using CuArrays

x = cu(rand(2))
y = cu(rand(2))
vcat(x,y)

Gives me warnings and error:

I built Julia 0.6.2 from source and am running on Ubuntu 16.04. GPU is 1060 GEFORCE (compute capability 6.1.0) and I am running CUDA 8.0 with CUDNN 7.0.5
Has anyone seen this error before? Any help would be greatly appreciated! :)

[MikeInnes]

Is this still the case on the latest release?

[DavidBegert]

Seems to work when I checkout to v0.5.0 of CuArrays.
Thanks!
