      Description

      clang sanitizer failed with:

      FAIL: test_wt2909_checkpoint_integrity
      ======================================
       
      check_results/127: session->open_cursor(session, "table:subtest", NULL, NULL, &maincur): No such file or directory
      FAIL test_wt2909_checkpoint_integrity (exit status: 1)
      

      This test runs a subprocess that populates a database (while enduring injected write failures), and then examines the resulting database. The subprocess created a stderr.txt file that contains:
