Yes.  (1) Launch the Carbon Emacs, (2) M-<, C-e, and hit the space bar
four times to move the cursor to the right fringe area of the first
line.  (3) C-x 2 to split the window.

Just after 2), I see a hollow box cursor (should be a filled one), and
3) makes all cursors disappear.  I couldn't reproduce these phenomena
on the X11 version.

By the way, bit-swapping in fringe.c is not needed for the mac port.
As a matter of fact, Carbon Emacs in CVS (without the image support
patches) has been displaying right arrows on the right fringe as left
arrows :-)

Additionally, if the start address of the bitmap data for each row
were word-aligned (by occupying 2 bytes for each row) for the mac
port, we would not need to create intermediate data for displaying
fringe bitmaps.  It would be worth considering if similar things also
happen in the w32 port.
