    Description

      The ex_col_store.c program from WT-7072 fails when compiled with the memory sanitiser. This is likely an internal problem not providing column store support. 

      Here is the link to the evergreen error https://evergreen.mongodb.com/task/wiredtiger_ubuntu1804_make_check_msan_test_48fd16f2247101b2af46661adeb3bfa37e2f9e63_21_01_28_02_50_31

      Steps to reproduce:

      1. Use the minimal reproducer (example_file.c) in the attachment.
      2. Set CC=clang CFLAGS="-fsanitize=memory" ../configure

      Acceptance criteria:

      Allow ex_col_store.c to run with memory sanitiser enabled.
