Hi Timour,

In regular maria-5.5, I get:

(gdb) wher 1
  #0  Item_func_like::select_optimize (this=0xa11c478) at /home/psergey/dev2/5.5-look7/sql/item_cmpfunc.cc:4739
  (More stack frames follow...)
(gdb) p args[1]
  $123 = (Item_singlerow_subselect *) 0xa1194a0
(gdb) p args[1]->used_tables()
  $124 = 0
(gdb) p args[1]->const_item()
  $125 = true

In 5.5-timour tree, I get:

  #1  0x0841a035 in Item_func_like::select_optimize (this=0xa109820) at /home/psergey/dev2/5.5-timour/sql/item_cmpfunc.cc:4739
(gdb) p args[1]
  $47 = (Item_singlerow_subselect *) 0xa106848
(gdb) p args[1]->used_tables()
  $49 = 0
(gdb) p args[1]->const_item()
  $51 = false

I also put a breakpoint in JOIN::get_examined_rows(), it is never hit. Can you
explain this effect?

BR
 Sergei
