As I said, there seems to be something up with your Julia, as it does not render the exception (anything in your startup.jl?)
Also, the error being thrown is one not known to the wrapped CUDA headers. Could you try the following to see the actual code:
julia> using CUDAdrv
[ Info: Precompiling CUDAdrv [c5f51814-7f29-56b8-a69c-e4d8f6be1fde]
julia> CUDAdrv.unsafe_cuCtxGetCurrent(Ref{CUDAdrv.CUcontext}())
CUDA_SUCCESS::cudaError_enum = 0x00000000
julia> Int(ans)
