      Description

      A simple PIVOT table test crashes the server while trying to connect back to execute the pivot query.

      Started with a clean MariaDB installation from the MariaDB repositories for Ubuntu Precise release.

      1. CREATE DATABASE test_pivot
      2. Create the empty table using the file 'test_pivot_2.sql' in the attached tarball.
      3. Load the data using LOAD DATA INFILE from the 'test_pivot_2.txt' file in the attached tarball.
      4. Create the pivot table using the 'my_pivot_2.sql' file in the tarball.
      5. Execute SELECT * FROM my_pivot_2;

      The client will show the following error message:
      ERROR 2013 (HY000): Lost connection to MySQL server during query

      See attached error log: bart-05.err
