I'm seeing point at point-max now, too, but I did see it at point-min
yesterday and also when I first tried again after reading your mail,
though, strangely, I can't reproduce that now.  I was testing with two
frames and switched back and forth between them, maybe that affects
point.

Yes, but the question is, how does point get there in Hydra?

That's probably a good idea; can you add them?  (AFAIK
dired-test-bug27243-03 hasn't failed in Hydra, though I can't access the
logs right now to check more recent builds, but I guess it's fine to add
more sanity checks.  As for replacing switch-to-buffer by
pop-to-buffer-same-window, I used the former in an attempt to mimic
typing `C-x b', which the recipes in the bug reports use, but since it's
not being called interactively, it's probably not a valid attempt
anyway.)
