Description:
When comparing CURDATE to a date data type in a table, the less than or equal to works:

event_post <= CURDATE()

whereas the greater than or equal to returns no results

event_date >= CURDATE()

This error does not occur in version 5.2.33 and was only found after migrating the database to a version 5.1.47.

How to repeat:
Two table fields of type date are set, one as a post date (when something was posted), and another as an event data (when the event occurs).  Making sure that the the post date is prior to CURDATE() and event date is after CURDATE().  Generate query to find all rows between the two dates.

Please, check if the same problem happens with current server version, 5.1.56, and send complete test case if it does.
