Bug lp:781508: Take relevant test cases from MySQL 5.6 feature preview trees 

Identified all test cases in the MySQL file subquery_mat.inc that are
not present in MariaDB. In total found 8 test cases for the following
MySQL bugs:
* BUG#49630 - not a bug in MariaDB, added test case
* BUG#52538 - not a bug in MariaDB, added test case (checked with VG)
* BUG#53103 - not a bug in MariaDB, added test case
* BUG#54511 - not a bug in MariaDB, added test case
* BUG#56367 - not a bug in MariaDB, added test case
* BUG#59833 - not a bug in MariaDB, added test case
* BUG#11852644 - not a bug in MariaDB, added test case
* BUG#12668294 - not a bug in MariaDB, added test case

All of these MySQL bugs are not present in MariaDB 5.3.

The comparison was based on the following version of
mysql-trunk:
