With CxxWrap fully relying on BinaryBuilder binaries now, this came up again in the tests: https://github.com/JuliaInterop/CxxWrap.jl/pull/274/checks?check_run_id=1622273928#step:5:54 I don't know if anyone reading this knows the GCC internals well enough to...

This is actually resolved upstream: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64243 But GCC 9.1 is still affected, any chance we could upgrade the 9 series to 9.3 and maybe add GCC 10 too? Where and...

I have no idea when and in what commit this was fixed, unfortunately.

I can confirm that setting `preferred_gcc_version` to version 10 fixes this.

Ah, yes, it was because of an old version, both examples run at the same speed now. I was using the runtime API because that's what the NVIDIA beginner's tutorial...

@cdsousa Done, see https://gist.github.com/barche/9cc583ad85dd2d02782642af04f44dd7#file-add_cuda-jl

I have just updated the gist (file `unifiedarray.jl`), I didn't realize that was still the old version, sorry

To confirm, I tried on my GTX 1060 and it still worked.

The issue is that you need to build both libcxxwrap-julia and the example code against Julia 1.9, since there is a binary incompatibility between 1.8 and 1.9. Unfortunately at this...
