I'm compiling Clang now to try to reproduce using a UBSan build (I'm on Ubuntu, though).

I'm not entirely familiar with how these sanitizer builds work... could the implication be that we're hitting undefined behavior at some point? Or is it just a red herring?

Note also that the "set([float('nan'), b'a', b'b', b'c', 'x', 'y', 'z'])" and "frozenset([float('nan'), b'a', b'b', b'c', 'x', 'y', 'z'])" tests seem to be working just fine... meaning their ordering on this buildbot is different under PYTHONHASHSEEDs 0 and 1 (as expected). It may still be a platform-or-configuration-dependent ordering, though.

Raymond: off the top of your head, are there any obvious reasons this could be happening?
