This is reproducible with emacs -Q.

Start ediff. Any pair of files/buffers will do, as long as they produce multiple
difference regions.

Hit "#f" to focus by regular expression. Enter "."  for both of the regular
expressions, then "y" to match on both buffers. (This results in a "focus" that
actually includes all the diffs, but that is just for simplicity - it is not
necessary in order to reproduce the bug.)

Use "n" a few times to advance through the first few difference regions. Then
try to use "p" to back up; instead of the previous diff you will be positioned
before the first one ("At start of <n> diffs").
