This is on NetBSD 11 amd64.

Interestingly, on NetBSD 11 on amd64 on an AMD Bulldozer or Zen 3, it 
compiles fine. On a Zen 4 or Zen 5, it has this issue.

Does anyone know OpenBLAS enough to know why?

Separately, are we inadvertently making binary packages that're optimized 
for the CPU on which they're compiled?

Thanks!
