      Description

      Build tested: 6.2.2-1

      I have attached scripts and data for reproducing the reported issues

      Run genData.sh to produce a 1 million row dataset.

      Scenario #1 (core dump)
      Steps to reproduce

      1. Use the create_t1.sql to create a 600-column table
      2. Use the cpimport.sh to load 1 million row dataset 50 times

      On the 3rd cpimport run, core dump occurred. I tried the test twice and got two different malloc() errors.

      malloc(): mismatching next->prev_size (unsorted)

      iteration=3
      Locale = en_US.UTF-8
      Using table OID 3837 as the default JOB ID

      Scenario #2

      1. Run createTables.sh to create 300 tables (t1-t300, 600 columns each). The script will insert two rows into each table.
      2. Run cpimport.sh to load data into t1 50 times.

      Eventually, error similar to the following will occur. The table will not be usable after that
