Bug#36443 Server crashes when executing insert when insert trigger on table

Browse Source 
The crash appeared to be a result of allocating an instance of Discrete_interval 
      automatically that that was referred in out-of-declaration scope.
                        
      Fixed with correcting backing up and restoring scheme of
      auto_inc_intervals_forced, introduced by bug#33029, by means of shallow copying;
      added simulation code that forces executing those fixes of the former bug that
      targeted at master-and-slave having incompatible bug#33029-prone versions.
