Steps to Reproduce Behavior

In Visual Fox Pro, create a program.

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

Run the program file.

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