Very interesting, indeed.
Best would be running only the failing test in a memory checker, but I don't think this is possible if you can't go physically on the machine. Will check with people here if someone can try to reproduce this.
I have a ppc64le VM if anyone wants to debug this hands-on. Just send me your public ssh key.

I can't repro crashes on Power8 either, but I did produce a bunch of failing regressiontests, see #2746, #2747. There may be something here that sometimes causes only wrong results and occasionally crashes too.
@Christoph: have the runs been repeated in the fedora system, do you see incorrect results in some cases?
