      Description

      Reproduce

      --source include/have_innodb.inc
      --source include/not_windows.inc
      --source include/not_embedded.inc
       
      let $d255=###################################################;
      let $d250=##################################################;
      let $d245=#################################################;
      --replace_result $d255 d255
      eval create database `$d255`;
      eval create table `$d255`.`$d245` (x int) engine innodb;
       
      # CREATE TABLE works
      eval create table `$d255`.`$d250` (x int) engine innodb;
      eval drop table `$d255`.`$d250`;
       
      # RENAME TABLE doesn't work
      --error ER_IDENT_CAUSES_TOO_LONG_PATH
      eval rename table `$d255`.`$d245` to `$d255`.`$d250`;
       
      # and even assertion-fails!
      eval rename table `$d255`.`$d245` to a;
       
      eval drop database `$d255`;
      drop table t;
      

      Result

      RENAME TABLE fails to rename to `$d255`.`$d250` while CREATE TABLE succeeds. RENAME TABLE from `$d255`.`$d245` fails with assertion.
