--- Comment #20 from Mathieu Malaterre <malat at debian dot org> ---
The Debian package highway 0.17.0-9 is not build with neon option (aka ARM7=
=3DOFF
in cmake), the code build just fine and test suite run fine (-O1):

*
https://buildd.debian.org/status/fetch.php?pkg=3Dhighway&arch=3Darmhf&ver=
=3D0.17.0-9&stamp=3D1657025640&raw=3D0

If you go through the logs of old compilation, you should fine the one with=
 -O2
at:

*
https://buildd.debian.org/status/fetch.php?pkg=3Dhighway&arch=3Darmhf&ver=
=3D0.17.0-2&stamp=3D1655882301&raw=3D0

I can also build and use it just fine on Debian porterbox `abel.d.o` which =
is:

```
