Run Emacs with the -Q option, create a new buffer, and put those
three lines there,
foo
bar
baz
type C-p C-p C-SPC M-> , and type `C-x n n' so that the last
two lines are visible. Then you will see C-n and C-p don't work.

This is evidently more fallout from enabling cache-long-scans: if you
set this to nil, C-n and C-p work again.

Thanks. I confirmed (setq-default cache-long-scans nil) helps.
I overlooked it is buffer-local.

No, this is cache-long-scans doing us a favor and exposing a bug in
our code that uses one of the caches.
Fixed in trunk revision 115190.
