Bug #49552 : sql_buffer_result cause crash + not found records

Browse Source 
in multitable delete/subquery

SQL_BUFFER_RESULT should not have an effect on non-SELECT 
statements according to our documentation.
Fixed by not passing it through to multi-table DELETE (similarly
to how it's done for multi-table UPDATE).
