Bug#998106: mpi4py: test_io.TestIOSelf failures on i386

[Drew Parsons]

Source: mpi4py
Version: 3.1.1-8
Severity: serious
Justification: debci
Control: forwarded -1 https://github.com/mpi4py/mpi4py/issues/105

mpi4py tests are failing on i386 debci.
e.g.
https://ci.debian.net/data/autopkgtest/unstable/i386/m/mpi4py/16315322/log.gz

The failing tests are file IO tests (test_io.TestIOSelf and test_io.TestIOWorld)
e.g.

The problem was already reported upstream, https://github.com/mpi4py/mpi4py/issues/105
It's affecting Redhat, not just Debian.


This is not a general 32-bit failure.  armhf is passing tests.


Probably severity: serious is overkill for this problem. The test
failure can be ignored for the purpose of package management by simply
skipping test_io.TestIOSelf and test_io.TestIOWorld on i386.  The
other 1172 mpi4py tests are passing on i386.

Patient: Doctor, it hurts when I do this.
Doctor: Then don't do that.
