mysql-test/r/kill.result: BUG#14851 test mysql-test/t/kill.test: BUG#14851 test sql/sql_class.cc: Debug prints are added. sql/sql_select.cc: Allocation of tmp_join fixed to involve constructor (it is not related to the bug directly but might cause other problems). Excluded posibility of tmp_table_param.copy_field double deletion (BUG#14851). sql/sql_select.h: JOINs constructor added, initialization of them fixed (it is not related to the bug directly but might cause other problems).
