ERROR: test_cubic (elephant.test.test_cubic.CubicTestCase) on 32 bit arches

[sanjayankur31]

We're building elephant for multiple arches for neurofedora. This one test fails on 32 bit architectures only. Here's the output from a failed i686 build:

BUILDSTDERR: ERROR: test_cubic (elephant.test.test_cubic.CubicTestCase)

• Failed i686 build: https://koji.fedoraproject.org/koji/taskinfo?taskID=35534431
• The complete build log for this i686 build is here: elephant-i686-failed-build.txt
• This file includes what the "buildroot" was composed of---versions of packages and so on: elephant-i686-failed-root.txt

Also fails on armv7hl:

• Failed armv7hl build: https://koji.fedoraproject.org/koji/taskinfo?taskID=35534721
• build log: elephant-armv7hl-failed-build.txt
• root log elephant-armv7hl-failed-root.txt

We're building against a git snapshot of neo, so maybe that's causing it. However, given that the test does not fail on 64 bit arches, it may not necessarily be the case. For completelness, here's an x86_64 build where the test did not fail:

• https://koji.fedoraproject.org/koji/taskinfo?taskID=35534537
• complete build log for this build: elephant-x86_64-passed-build.log
• complete root log: elephant-x86_64-passed-root.log

We've disabled this test temporarily. Could someone please have a look?
The spec file for the rpmbuild is here: https://src.fedoraproject.org/rpms/python-elephant/blob/master/f/python-elephant.spec

Please note that these failed builds will be removed from the build system in a few days, but I can always re-run them if more information is required.
