>OpenCL.Device(Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz But that's the CPU OpenCL implementation, right?

Maybe I should just not test the CPU anymore - at least as long as I don't have time to fix those issues and I know that half of the...

I've seen this issue before, not really sure what to do about it. Which one of those devices did you use to create the array? ```Julia A = CLArray(...) CLArrays.device(A)...

Ah, I need to have a better look at it, but maybe we just don't filter non fatal errors. https://github.com/JuliaGPU/OpenCL.jl/blob/master/src/context.jl#L109 As you can see, there should be an error information,...

Ha, OpenCL.jl itself seems to do that: https://github.com/JuliaGPU/OpenCL.jl/blob/master/src/context.jl#L148 I haven't written that code, so I'm not sure why it's structured in that way, and why on some platforms it just...

this is definetely a bug! I'll look into it on monday when i'm back at a pc with opencl!

Can you try https://github.com/JuliaGPU/CLArrays.jl/pull/18 (which just got merged and I will tag it now! Deps should be tagged but will need a `Pkg.update()`). All your tests pass on those tags...

Hm this works for me! Did you do `Pkg.update()` ? I don't see it in your log ;)

Are you using this with an OpenCL CPU driver? I have been figthing with issues related to different alignment for intel/amd cpu opengl drivers... What's the output of this: ```...

You might be able to get around this problem if you can insert some padding ;) E.g. try: ```Julia struct WithTuple a::Int32 pad::Int32 # might be even more efficient b::Tuple{Int32,Int32}...
