A query with a group by and having clauses could return a wrong result set if the having condition contained a constant conjunct evaluated to FALSE. It happened because the pushdown condition for table with grouping columns lost its constant conjuncts. Pushdown conditions are always built by the function make_cond_for_table that ignores constant conjuncts. This is apparently not correct when constant false conjuncts are present.

The bug was as follows: When merge_key_fields() encounters "t.key=X OR t.key=Y" it will try to join them into ref_or_null access via "t.key=X OR NULL". In order to make this inference it checks if Y<=>NULL, ignoring the fact that value of Y may be not yet known. The fix is that the check if Y<=>NULL is made only if value of Y is known (i.e. it is a constant). TODO: When merging to 5.0, replace used_tables() with const_item() everywhere in merge_key_fields().

after merge. Concurrent read and update of privilege structures (like simultaneous run of SHOW GRANTS and ADD USER) could result in server crash. Ensure that proper locking of ACL structures is done. No test case is provided because this bug can't be reproduced deterministically.

The reason of the bug is in that `get_var_with_binlog' performs missed assingment of the variables as side-effect. Doing that it eventually calls `free_underlaid_joins' to pass as an argument `thd->lex->select_lex' of the lex which belongs to the user query, not to one which is emulated i.e SET @var1:=NULL. `get_var_with_binlog' is refined to supply a temporary lex to sql_set_variables's stack.
