[Bug 2024207] [NEW] s390x autopkgtest regression of libflame vs glibc in Jammy

[Simon Chopin]

Public bug reported:

The libflame autopgktests on Jammy are now failing on s390x against
glibc 2.35-0ubuntu3.2.

It's triggering a timeout in the numpy-with-libflame test suite. To
reproduce, you need python3-numpy, libflame1 and libflame-dev install.

The issue seems to be in
numpy/f2py/tests/test_compile_function.py::test_f2py_init_compile. To be
able to investigate this, I had to change /usr/lib/python3/dist-
packages/numpy/_pytesttester.py, line 183:

-           pytest_args += ["-m", label]
+           pytest_args += ["-k", label]

and then I used the following Python script to reproduce:

#!/usr/bin/python3

import numpy as np
np.test("full", verbose=3, extra_argv=['numpy/f2py/tests/test_compile_function.py::test_f2py_init_compile'])

I haven't managed to go further yet, except that I know that the bug
doesn't seem to trigger if running under strace.
