Comment 2 for bug 424553

I think 5.1 tag should be removed and priority reduced.

Other than the mentioned testcase (which we can live without), I have never saw anything or anybody to use @@myisam_data_pointer_size value to limit temporary table size. If there is a real need to set such limit, we should add a separate variable, e.g. @@disk_temp_table_size.

With regards to inability to check the USE_MARIA_FOR_TMP_TABLES setting from SQL, that doesn't seem to be high priority (haven't seen anybody to build MariaDB with MyISAM temp.tables for a while, there are no known issues with MyISAM vs Maria temp.tables, etc.)
