BUG: segfault on i386 in special test_kolmogorov.py TestSmirnovp

[drew-parsons]

Describe your issue.

As discussed in #16646 , a build of scipy 1.8.1 for i386 with debian unstable crashes when running tests. This segfault is new, the build was previously successful. The segfault started after trying to apply the pythran patch from #16646, but there's no reason to think that patch itself triggered it. Debian recently switched from gcc 11 to gcc 12, so possibly that is related.

Reproducing Code Example

Bug occurs when running tests during a debian build on i386, so reproduced (on a debian i386 system) with

apt-get source scipy
cd scipy-1.8.1
dpkg-buildpackage

If the problem is universal, it might show up with

./runtests.py -v -s special -- -k "TestSmirnovp"

Can check after build is complete with

python3 ./runtests.py -v -n -s special -- -k "TestSmirnovp"

I think that that functionality was already problematic on 32-bit indeed, we simply xfailed the test but never fixed the problem: gh-9509.
