gpu_call with @cartesian index

[myroslavpidkuyko]

gpu_call does not seem to work for multidimensional grids
when I run the simple following code

using CLArrays, GPUArrays
n_b = 100
n_h = 10
n_m = 100
grid = CLArray(zeros(Float32, n_m, n_h, n_b))
gpu_call(grid, (grid, UInt32(n_m), UInt32(n_h), UInt32(n_b))) do state, grid, n_m, n_h, n_b
idx3 = GPUArrays.@cartesianidx grid
idx_m = idx3[1]
idx_h = idx3[2]
idx_b = idx3[3]
return
end

gives
Error in Expr rewrite! MethodError(all, (Transpiler.#27, Any[1]), 0x0000000000005845)

Expression resulting in the error:
idx_m::UInt32 = (Main.getindex)(idx3::Tuple{UInt32,UInt32,UInt32}, 1)::UInt32

any idea why this is happening and how to fix it?
