New CUDA.jl version circa v5 seems to break many functions that previously worked with CuArrav. eg

```julia
a = [1 2; 3 4] |> cu
diff(a; dims=1)

```

now raises LLVM IR error. Why is this?

You’ll have to elaborate, at the very least by posting the error message. The snippet you posted works fine here.

Thanks worked after upgrading from julia 10.1 to 11.0 🙂 for the record errors said unsupported dynamic function invocation but seemed to arise stochastically depending on GPU state…

Latest stable version of Julia is 1.10.4, I think you mixed up a bit the version numbers?
