Hello I am running extremely simple kernel as shown below and get and error pointing to CuDynamicSharedArray

```julia
using CUDA
ff = CUDA.zeros(3)
function gggg(ff)

  shmemblockDataa = @cuDynamicSharedMem(Float32,(1,2))
    return
end
@cuda threads=(32,2) blocks=2 gggg(ff)
ff[1]

```

ERROR

```julia
ERROR: a exception was thrown during kernel execution.
