Working in 11.2.0.3 different memory corruption related errors:

ORA-07445: exception encountered: core dump [__intel_new_memset()+2660]
ORA-00600: internal error code, arguments: [17114]
ORA-00600: internal error code, arguments: [kghfrempty:ds]

are reported while gathering statistics with command:

dbms_stats.gather_table_stats (lr_all_tab_statistics.owner
                               ,lr_all_tab_statistics.table_name
                               ,estimate_percent   => dbms_stats.auto_sample_size
                               ,method_opt         => 'FOR ALL INDEXED COLUMNS SIZE AUTO'
                               ,degree             => pi_degree
                               ,cascade            => true
                               ,granularity        => 'AUTO');

The errors are consistently reproduced when the statistics are gathered from the Scheduled Job and randomly when manually executed.
