This assertion would occur if UPDATE was used to update multiple tables containing an AUTO_INCREMENT column and if the inserted row had a user-supplied value for that column. The assertion could then be triggered by the next statement. The problem was only noticeable on debug builds of the server. The cause of the problem was that the code for multi update did not properly reset the TABLE->auto_increment_if_null flag after update. The flag is used to indicate that a non-null value of an auto_increment field has been provided by the user or retrieved from a current record. Open_tables() contains an assertion that tests this flag, and this was triggered in this case by ALTER TABLE. This patch fixes the problem by resetting the auto_increment_if_null field to FALSE once a row has been updated. This bug is similar to Bug#47274, but for multi update rather than INSERT DELAYED. Test case added to update.test.
