With the fix for <Bug 19438874> installed, when doing a DELETE statement from a table that has a functional index (DESC index) getting:
ORA-600: internal error code, arguments: [qkaffsindex1], [], [], [], [],[], [], [], [], [].

Same happens if the DELETE on the table is using the index_ffs hint for functional index (DESC index).

In 12c database releases this error can occur if "_replace_virtual_columns"=FALSE or by disabling the fix 9929609 ("_fix_control" = '9929609:off') if the functional index is a descending index.
