Describe the bug

While working on conda-forge/scikit-learn-feedstock#123, I found that some tests segfault specifically on ppc64le with PyPy (but not with other runtimes on ppc64le, or with PyPy on other platforms). I gather that there's no CI for PyPy here, but in any case, @rth asked me to open a bug here.

Here are the logs from the CI run .

Thanks @h-vetinari! PyPy + ppc64le is somewhat exotic, but segfaults would still be worth investigating.

FWIW there are segfaults with PyPy even on x86_64 #17994

There was a bug in ppc that was fixed after the recent 7.3.2 release. Either skip ppc testing on PyPy until the next release or use a nightly

Closing after PyPy official support has been dropped #29128

@lesteve lesteve closed this as not planned Won't fix, can't repro, duplicate, stale Jun 3, 2024
