Yes.

This is something to do with my change:

2004-03-26  Masatake YAMATO  <address@hidden>

        * buffer.c (fix_start_end_in_overlays): Rename fix_overlays_in_range.

        * lisp.h (fix_start_end_in_overlays): Likewise.

        * insdel.c (adjust_markers_for_insert): Call fix_start_end_in_overlays.

        * editfns.c (Ftranspose_regions): Likewise.

How do you think make evaporate overlay's property t by default(when 
make-overlay)?

    `evaporate'
         If this property is non-`nil', the overlay is deleted automatically
         if it becomes empty (i.e., if its length becomes zero).  However,
         if the overlay is _already_ empty, `evaporate' does not delete it.
