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 happening in function tree: Sugar stack trace: [1] #149(CLArrays.KernelState, CLArrays.DeviceArray{Float32,3,Transpiler.CLIntrinsics.GlobalPointer{Float32}}, UInt32, UInt32, UInt32)

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