Thanks for the overview.

Notice that this happened on gcc67, so on the Ryzen CPU (and nowhere
else), so I'm afraid the Ryzen crashes are _STILL_ not fixed. I'll stop
the autobuilder again.

Yes, I guess this is the best solution for 2018.02.

Once more on gcc67 (and no other autobuilders), please ignore.

Agreed, but what are the alternatives? Make the package unavailable for
x86 or drop it completely, as it is afaik dead upstream.

Or deprecate qt4?

Agreed, considering how close we are getting to 2018.02.
