Hah, that's useful info. Seems like it must be incorrect code
generated by JIT.

arm64, eh? I wonder if that's buggier than the Intel code paths.
I tried and failed to reproduce this on Fedora 35 on aarch64,
but that has what I think is a newer LLVM version:
clang-13.0.0-3.fc35.aarch64
clang-libs-13.0.0-3.fc35.aarch64
clang-resource-filesystem-13.0.0-3.fc35.aarch64
gcc-11.2.1-9.fc35.aarch64
gcc-c++-11.2.1-9.fc35.aarch64
llvm-13.0.0-4.fc35.aarch64
llvm-devel-13.0.0-4.fc35.aarch64
llvm-libs-13.0.0-4.fc35.aarch64
llvm-static-13.0.0-4.fc35.aarch64
llvm-test-13.0.0-4.fc35.aarch64
Don't think I can readily install anything as old as LLVM 9 ...
