See $URL for upstream report. For a quick fix we could filter-flag -march=native until upstream has figured out why this happens.

This has been fixed with upstream commit: https://github.com/google/highway/commit/0d4e6311b38467f31e8c817aa7e1d1549d1e699e
This is fixed in 1.0.1 (https://github.com/google/highway/releases/tag/1.0.1).
Yes, I am planning to replace 1.0.0 with the 1.0.1
