The following bugs are fixed:

Bug #31860: Server crashes after inserting into InnoDB table with auto_increment column
  In the Bug 16979 fix there was an erroneous assertion that
  autoincrement columns can't contain negative values. With the fix, the
  autoincrement table counter is set to 0 if the maximum value read from
  the autoinc column index is negative.
