Description:
After updating to 5.1.32 from 5.1.30, we can no longer limit the memory consuption, with MySQL taking over 50G of memory for queries that would formerly take less than 20G.  All parameters are same, and lowering key_buffer_size does not have any impact.

How to repeat:
run queries that combine multiple large databases and watch the memory get sucked up.

Thank you for the report.

Please provide repeatable test case: SHOW CREATE TABLE, dump of tables or at least SHOW TABLE STATUS output and problem query.
