#7 ordereddict.c:807: dictresize: Assertion `newotablep != oldotablep' failed

[Anthon van der Neut]

I'm trying to build ruamel.ordereddict-0.4.9 on Gentoo using gcc-5.4.0 and python-2.7.12. The build itself goes fine, however the test suite fails with:

>>> Test phase: dev-python/ruamel-ordereddict-0.4.9

Here the kernel log from the dump:

I'm not really sure where I should start searching for the issue. I found that Fedora is building and testing the same sources fine using gcc-7.0.1 and python-2.7.13 (see e.g. https://kojipkgs.fedoraproject.org//packages/python-ruamel-ordereddict/0.4.9/4.fc26/data/logs/x86_64/build.log)

I attached my build.log if you need more information. Anyone having a hint what is going wrong here?
