This is an auto-filed bug because sci-libs/fflas-ffpack fails tests.
The issue was originally discovered on amd64, but it may be reproducible on other arches as well.
If you think that a different summary clarifies the issue better, feel free to change it.
Attached build log and emerge --info.
If you need further logs, feel free to ask.

I cannot reproduce it. Apart from the blas/lapack you used, the only thing that may be interesting is your hardware.
this is an Amazon EC2 instance

Thought it could be something like that. I'll have a look upstream and point them here if I cannot find anything.
It looks like it could be nearly identical to a report upstream by conda people

We can disable this test in the meantime if it's affecting other people and no better solution presents itself. Patch attached so I don't have to re-do it later.
