Description Greg V 2020-07-21 22:16:08 UTC 
With errors like:

    nearPos = nearPos.unproject(viewMatrix, projectionMatrix, viewport);

Indeed, it also fails when I set it to znver1 here.

Could you verify that you also get 

  Use SSE2 instructions .................. yes
  Use AVX2 instructions .................. no

in the configure output?

Yes
Comment 4 break19 2020-10-14 10:26:21 UTC 
also hitting this bug on -current with cputype=znver1:

# uname -a
FreeBSD zenstation 13.0-CURRENT FreeBSD 13.0-CURRENT #1 494ba3d79-c119(master): Fri Oct  9 16:11:27 CDT 2020     root@zenstation:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG  amd64
Comment 5 eborisch+FreeBSD 2020-11-23 21:39:07 UTC 
Adding

CPUTYPE= ivybridge   # (Select the most recent CPU without AVX2 support)

lets it build, but it would be nice to enable avx2 on local builds where it the instructions are supported.
Comment 6 Tobias C. Berner freebsd_committer 2020-11-24 05:24:56 UTC 
(In reply to eborisch+FreeBSD from comment #5)

Yeah, someone should invest some time in why the AVX2 detection fails.
Patches, welcome :)
