Steps to Reproduce Behavior
---------------------------

1. In Visual Fox Pro, create a program.

2. Add the following code to the program:

  SET SAFETY OFF
  SET COLLATE TO "General"
  CREATE TABLE test (nID N(5))
  FOR T=1 TO 10000
  	INSERT INTO test VALUE (T)
  ENDFOR
  SELECT * FROM test WHERE nID NOT IN (SELECT * FROM test)
  SET SAFETY ON
  ? RECCOUNT()
  CLOSE ALL
  DELETE FILE test.DBF

3. Run the program file.

Note that the SQL-SELECT statement and RECCOUNT() function return 24 records,
when no records should be returned.
