[Debian-pan-maintainers] Bug#1018811: pyfai: autopkgtest regression on armel and i386

[Graham Inggs]

Source: pyfai
Version: 0.21.3+dfsg1-1
Severity: important
User: debian-ci at lists.debian.org
Usertags: regression

Hi Maintainer

The autopkgtests of pyfai have regressed on armel and i386 [1][2],
where they passed previously (see results of e.g. 0.20.0+dfsg1-3).  I
have copied what I hope is the relevant part of the log below.

These test failures are known upstream, as can be seen in the
following code snippets.

pyFAI/test/test_histogram.py:
@unittest.skipIf(UtilsTest.low_mem, "test unreliable on 32bits processor")
def test_count_csr(self):

pyFAI/test/test_histogram.py:
@unittest.skipIf(UtilsTest.low_mem, "test unreliable on 32bits processor")
def test_numpy_vs_cython_vs_csr_2d(self):

pyFAI/test/test_csr.py:
@unittest.skipIf(UtilsTest.low_mem, "test unreliable on 32bits processor")
def test_2d_nosplit(self):

This was noticed in Ubuntu, when the upload of glibc 2.36 caused the
same tests to start failing on armhf.

Regards
Graham
