Before this patch the crash occured when a single row dataset is used and Item::remove_eq_conds() is called for HAVING. This function is not supposed to be called after the elimination of multiple equalities. To fix this problem instead of Item::remove_eq_conds() Item::val_int() is used. In this case the optimizer tries to evaluate the condition for the single row dataset and discovers impossible HAVING immediately. So, the execution phase is skipped.
