Growth in PGA memory usage when gather_table_stats gets executed in a PL/SQL loop (e.g. anonymous block).
The memory allocated during gather_table_stats() is getting freed at the end of anonymous/PLSQL block (user call).
1. Setting "_fix_control"='20424684:OFF' should not reproduce the problem.
2. Issue should be growth in PGA memory (not a leak) while executing gather_table_stats()
alter session set "_fix_control"='20424684:OFF';
