Yes, the stack trace is the same.  The odd part is that I was consistently
seeing it until next-20180626, but it evaporated in sometime between that and
next-20180703. I suspect it has to do with the fact that -0626 was compiled
with gcc 8.1.1-3.fc29, but -0703 with 8.1.1.-4.fc29. As such, I probably won't
be able to test the patch without downgrading gcc....
