WIP: Re-enable PROPACK tests

[h-vetinari]

The PROPACK tests were disabled in https://github.com/scipy/scipy/pull/15479 to unblock the release of 1.8.0. Still, we should fix this, so opening this PR to try to help iterate. Happy to play with any upstream commits / PRs (including submodules) here.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

[h-vetinari]

As expected, this essentially reproduces the state from 1.8.0rc3:

variant	blis	mkl	netlib	openblas	sum**
linux / x86	✔️	✔️	✔️	✔️	-
linux / aarch	➖	➖	✔️	✔️	-
linux / ppc64le	➖	➖	✖️	✖️	6F
osx / arm	➖	➖	✔️	✔️	-
osx / x86	✔️	✔️	✔️	✔️	-
win/ x86	💥	💥	💥	💥	12S
sum**	3S	3S	3S/3F	3S/3F	12S/6F

** sum of Segfaults (S), Failures (F), resp. Timeouts (T); out of a total of 54 CI combinations being tested

This is on my radar, just swamped recently and will pick this back as soon as I can

No worries, there's no rush. I just wanted to open the PR for support and as a reminder for us all.

@mckib2 Given that 1.8.1 seems to be materializing, I just wanted to double-check that I haven't missed any potential updates regarding PROPACK? Guessing we retarget 1.8.2 / 1.9.0?

So relative to https://github.com/conda-forge/scipy-feedstock/pull/224, this has no increase of test failures, and certainly all the propack segfaults on windows are gone 🤩 🥳

[h-vetinari]

Broken aarch/ppc builds have nothing to do with propack, investigating in https://github.com/conda-forge/scipy-feedstock/pull/232

[h-vetinari]

OK, taking the last results of https://github.com/conda-forge/scipy-feedstock/pull/224 as a baseline (minus https://github.com/scipy/scipy/issues/18371, which got fixed in #233) and then switching on propack again, the results are as follows

variant	accelerate	blis	mkl	netlib	openblas
linux / x64	➖	✔️	✔️	✔️	✔️
linux / aarch64	➖	➖	➖	✔️	✔️
linux / ppc64le	➖	➖	➖	✔️	✔️
osx / arm	❔	➖	➖	❔	❔
osx / x64	✔️	✔️	❌	✔️	✔️
win / x64	➖	❌	❌	❌	❌

Notable:

• the patches in #233 were only backported on unix, as they caused build failures on windows
• this time also re-enabled the tests that were skipped on windows in https://github.com/scipy/scipy/pull/16513
• failures differ wildly per run, with qualitative differences between CPython & PyPy (what?!)
• the "failure surface" on OSX+MKL is the same as for windows + all blas implementations (this is really surprising to me too)
• this is even more surprising given how different the builds are (osx patched on meson, windows unpatched on distutils)
• finally, the number of failures in sparse/linalg/tests/test_propack.py::test_svdp on osx+mkl+meson+CPython (without enabling PROPACK) is tightly bounded between 11-12, now it fluctuates between 3-9 failures?!
• so somehow, switching on PROPACK reduces the number of test failures for this?!?

In more detail:

• Very bizarre behaviour on osx+mkl. Aside from the fact that the failures of sparse/linalg/tests/test_propack.py::test_svdp & sparse/linalg/tests/test_propack.py::test_examples were shown to be due to meson in https://github.com/conda-forge/scipy-feedstock/pull/224, after backporting the latest patches we now see wildly differing errors per Python version and implementation, seemingly at random. It's also bizarre to me that only ever 15 tests fail per run, even though there's a total of ~50 that are possible
• The picture is similar on win+blis, as in: wildly fluctuating test failures, which also include some (but not always all!) failures due to reverting the skips for the complex tests. Here one run has 31/43 failures, the others are 10-17.
• It's notable that the union of all test failures for both these cases are effectively the same (up to one extra failure that only appears on windows), IOW: the "failure surface" is the same.
• As in https://github.com/conda-forge/scipy-feedstock/pull/224, sparse/linalg/tests/test_propack.py::test_svdp & sparse/linalg/tests/test_propack.py::test_examples only fail on CPython; PyPy only has failures for sparse/linalg/_eigen/tests/test_svds.py::Test_SVDS_PROPACK::test_svd_simple, but more of them each run.

osx + mkl: 13-15 failures out of 42, at random

I probably know what the root cause is. It's related to the ABI wrappers, so it makes sense that it only shows up with MKL. Basically, the use of wcdotc in PROPACK is completely wrong, and may produce arbitrary garbage. That things pass with Accelerate is just luck, I think it zero-initializes some data rather than grab random memory.
