Issue

I feel like I'm hitting

scipy/scipy#19831
scipy/scipy#19909

I'm wondering if we could backport 19909

Thanks for the report! 🙏

I've backported the PR in #268 and started the LAPACK flavour testing in #267 (which should give a clearer picture).

[h-vetinari]

Just merged #268, builds should be available in a few hours.

[hmaarrfk]

Is there any sense in repo patching? If so. How far back do we go?

[h-vetinari]

Good point. I think adding openblas <0.3.26 as run_constrained: could be done basically as far back as we want, without real risk of breaking something.
