GCC-13 works as expected. Turns out to be a UB case in highway source code.

Currently working on PR/111231. cresult is difficult to work with as

Package: g++-13
Version: 13.2.0-2
Forwarded: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110643
Affects: src:highway

I am getting some odd behavior for unit test of highway. I believe
there is some wrong-code generation using g++ + -O1.
