OPERATIONAL DEFECT DATABASE

This issue was introduced by the changes from d6ad188 as part of SERVER-33221 and therefore only affects the master branch. The "aggregate" command uses DBDirectClient to perform the insert operations as part of the $out stage but isn't present in cmdWhitelist. Thread 76 "conn2" received signal SIGSEGV, Segmentation fault.
