2 errors, both the same and related to `linalg.jl`

```julia-auto
Error in testset gpuarrays/linalg/core:
Error During Test at /home/rogerp/.julia/packages/GPUArrays/E99Fj/test/testsuite/linalg.jl:320
  Test threw exception
  Expression: compare(f, AT, A_empty, d)
  DivideError: integer division error

```

Is this something I’ve done? I don’t see anyone else reporting this issue.

Happy to post the whole output but I’ve forgotten how.

Roger

Probably fixed by [Return early (don't kernel launch) for copytrito and zero-sized arrays by kshyatt · Pull Request #660 · JuliaGPU/GPUArrays.jl · GitHub](https://github.com/JuliaGPU/GPUArrays.jl/pull/660)

Yes, that’s fixed it. `GPUArrays v11.3.0 ⇒ v11.3.1`

Thank you.
