Richard, I am using the latest gcc-12 update from doko@d.o:

*
https://tracker.debian.org/news/1363780/accepted-gcc-12-1220-3-source-into-=
unstable/

I can reproduce the failing test:

*
https://buildd.debian.org/status/fetch.php?pkg=3Dhighway&arch=3Darmhf&ver=
=3D1.0.2%7Egit20220901.9b3bd6d-2&stamp=3D1664289672&raw=3D0

But I cannot reproduce it using gcc-snapshot:

* https://packages.qa.debian.org/g/gcc-snapshot/news/20220920T113715Z.html

Let me know if you want more info=
