Description:
This bug simply still exists in the newest release of MySQL Community Edition.  We have some large MERGE tables that receive the error stated in the prev bug report whenever they are read or written to.  We have rebuilt the MERGE tables many times with the same results.  The error occurs when running mysql_upgrade also.  Had to revert to 5.0.27 again.

I am very sorry.  This error is general to many different MERGE problems and I was led to believe it may still be the previous bug referred to.  The issue was caused by several tables included in the large merge table mentioned having indexes out-of-order from the other tables. I did not think this was an issue as it did not cause any errors in 5.0.26.  I have remedied the indexes in the tables and the MERGE tables work great in 5.0.41 now.  I have no issues to report, this bug report may be deleted.
