      Bug #58426 Crashing tests not failing as they are supposed to on Solaris 10 debug
        
      On this platform we seem to get lots of other signals
      while waiting for SIGKILL to be delivered.
      
      Solution: use sigsuspend(<all signals blocked>)
     @ dbug/dbug.c
        New function _db_suicide_() which does kill(myself, -9) and then waits forever.
     @ include/my_dbug.h
        Let DBUG_SUICE wait forever until the KILL signal is delivered, and process dies.

      Bug#39828 : Autoinc wraps around when offset and increment > 1
      Auto increment value wraps when performing a bulk insert with
      auto_increment_increment and auto_increment_offset greater than
      one.
      The fix:
      If overflow happened then return MAX_ULONGLONG value as an
      indication of overflow and check this before storing the
      value into the field in update_auto_increment().
     @ mysql-test/r/auto_increment.result
        test case
     @ mysql-test/suite/innodb/r/innodb-autoinc.result
        test case fix
     @ mysql-test/suite/innodb/t/innodb-autoinc.test
        test case fix
