unknown 1164e2bc7a Bug#33851 Passing UNSIGNED param to EXECUTE returns ERROR 1210 ...

The problem is that passing anything other than a integer to a limit
clause in a prepared statement would fail. This limitation was introduced
to avoid replication problems (e.g: replicating the statement with a
string argument would cause a parse failure in the slave).

The solution is to convert arguments to the limit clause to a integer
value and use this converted value when persisting the query to the log.
