--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.

#ifdef ENABLE_CHECKING
  /* Verify that estimated growth match real growth.  Allow off-by-one
     error due to INLINE_SIZE_SCALE roudoff errors.  */
  gcc_assert (!update_overall_summary || !overall_size || new_edges_found
              || abs (estimated_growth - (new_size - old_size)) <= 1
              || speculation_removed
              /* FIXME: a hack.  Edges with false predicate are accounted
                 wrong, we should remove them from callgraph.  */
              || predicated);
#endif

triggers again...

(gdb) p estimated_growth
$1 = 5
(gdb) p new_size
$2 = 20
(gdb) p old_size
$3 = 13

off-by-two.
