BUG#14593883-REPLICATION BREAKS WHEN SET DATA TYPE
COLUMNS ARE USED INSIDE A STORED PROCEDURE Problem: The operator '=' overload method inside 'String' class is not coping str_charset member from R.H.S object to L.H.S object. Hence charset is wrongly set while using string assignments Analaysis: The above mentioned problem is identified while doing the analaysis of bug#14593883. Though the test scenario mentioned in the bug page is not an issue in mysql-5.1 code, the actual root cause ie., "str_charset member is not copied" exists in the mysql-5.1 code base. Fix: Handle coping str_charset member in operator '=' overload method. sql/sql_string.h: Handled coping str_charset member in operator '=' overload method.
