      Relevant snipped of test case extracted below:

      scoped_ptr<HarnessHelper> harnessHelper( newHarnessHelper() );
scoped_ptr<SortedDataInterface> sorted( harnessHelper->newSortedDataInterface() );

scoped_ptr<OperationContext> opCtx( harnessHelper->newOperationContext() );

WriteUnitOfWork uow( opCtx.get() );
ASSERT_OK( sorted->insert( opCtx.get(), key1, loc1, false ) );
ASSERT_OK( sorted->insert( opCtx.get(), key1, loc2, true /* allow duplicates */ ) );
ASSERT_OK( sorted->insert( opCtx.get(), key1, loc3, true /* allow duplicates */ ) );
uow.commit();

scoped_ptr<SortedDataInterface::Cursor> cursor( sorted->newCursor( opCtx.get(), 1 ) );
cursor->locate( key1, loc2 );

vector<const BSONElement*> keyEnd( 1 );
vector<bool> keyEndInclusive( 1 );

cursor->advanceTo( key1, 1, false, keyEnd, keyEndInclusive );
ASSERT_EQUALS( key1, cursor->getKey() );
ASSERT_EQUALS( loc3, cursor->getDiskLoc() );

      Instead, the cursor is positioned at (key1, loc1), i.e. the first occurrence of the specified key in the index.
