Crap.

And 4.9.75 works for you just fine?  Same with 4.15-rc6?

I'm wondering if this is some crazy gcc thing, given the ancient age of
what you are using (gcc 4.8.5).  I haven't used 4.x in many many years,
is this what comes with RHEL6?  What is the "base" distro you are
building this on, and anything special about the hardware being used
here?

Or is this a virtual machine?  I've been seeing too many different
crashes lately to keep them all straight, sorry...

thanks,
