This is an auto-filled bug because dev-python/pylibacl fails tests. The issue was originally discovered on ppc64, but it may be reproducible on other arches as well. Attached build log and emerge --info.

That's curious. I wouldn't think of PPC64 the kind of arch likely to trigger random segfaults.
Created attachment 636190 [details] build.log (Talos II) Same failure on a POWER9 machine with a more recent toolchain.
Please try 0.6.0.
