Since the last message I posted, I'm now also seeing this test fail, though I get a segfault instead. I bisected this to commit a555abc56d5270cebe94f904189526d7ac433a94 ("Fix order of faces in 'face-list'"). I'm pretty surprised by this, since that patch is *very* simple, but I can reliably segfault with it, and never segfault without it. I'll keep digging to see what's going on here.
