A wrong order of statements in QUICK_GROUP_MIN_MAX_SELECT::reset caused a crash when a query with DISTINCT was executed by a loose scan for an InnoDB table that had been emptied. mysql-test/r/innodb_mysql.result: Added a test case for bug #26159. mysql-test/t/innodb_mysql.test: Added a test case for bug #26159. sql/opt_range.cc: Fixed bug #26159. A wrong order of statements in QUICK_GROUP_MIN_MAX_SELECT::reset caused a crash when a query with DISTINCT was executed by a loose scan for an InnoDB table that had been emptied. For an empty table quick_prefix_select->reset() was not called at all and thus some important initialization steps were missing.
