I guess you're building from https://github.com/stellar-group/libgeodecomp, right? I've just done a manual push from https://github.com/gentryx/libgeodecomp to the Ste||ar Group repo, this didn't happen automatically as the builds aren't green ATM (CUDA support broken in HPX, possibly other bugs in LGD).

Also, please keep the bug reports coming if you discover more issues with AVX512. I wonder how this typo got pushed in the first place as we should be testing this code path.

I am building from 14af9ad on https://github.com/gentryx/libgeodecomp and having the exact same problem. I just rebuilt it to make sure.

Confirmed. Apparently I was too stupid to merge the bundled version of LibFlatArray correctly, sorry about that. Could you retry with ba45a35 ? (should be in both repos)
