Interesting.
Well, would you be able to help figure out exactly what's going on in:
http://lists.gnu.org/archive/html/qemu-devel/2012-12/msg03233.html
and the thread leading up to it?
Now, I don't *know* that this is an emulation failure -- the linux-user-test
binary certainly isn't aware of enhanced virtual addresses. So it's
possible that (older?) binaries can't cope with more than 2GB.
Alternately, it really is a translation problem somewhere...
