Got the backtrace, going to post on #51589. Have we tried asking @seberg for help? Didn't ask yet, was going to try to get this down to a MRE, but got sidetracked. Hmmmmpf, some other PRs still seem to fail in much the same way?  Seems my fix may have not been complete. > Hmmmmpf, some other PRs still seem to fail in much the same way? Seems my fix may have not been complete.

We cache our dependencies, I'll just cleared the cache, and now we're hitting compile failures because of the latest Cython 3 beta on our numpydev build.

I'll let you know if the fix works. @seberg Looks like the segfaults have disappeared. We do have some other failures, but those seem Cython related.

Thanks for the quick fix.
