> timestamp: Mon 2009-10-19 16:55:04 +0300
> message:
> Bug #47788: Crash in TABLE_LIST::hide_view_error on
> UPDATE + VIEW + SP + MERGE + ALTER
>
> When cleaning up the stored procedure's internal
> structures the flag to ignore the errors for
> INSERT/UPDATE IGNORE was not cleaned up.
> As a result error ignoring was on during name
> resolution. And this is an abnormal situation : the
> SELECT_LEX flag can be on only during query execution.
>
> Fixed by correctly cleaning up the SELECT_LEX flag
> when reusing the SELECT_LEX in a second execution.
