# The following tests are problematic and skipped:
# - Meson's python module always returns the default interpreter, which makes
#   Cython related tests fail on non-default python versions
# - numpy.distutils is still shipped because of Python 3.11, which makes the
#   test_all_modules_are_expected test fail with Python 3.12+ (where it is
#   supposed to be dropped).
# - Some f2py tests have architecture-specific failures. Further investigation
#   is needed.
# - There seems to be an issue with floating point exceptions on armhf/armel
# - At least one mips64el buildd has issues with NaN values
