      Our ASAN variant in the evergreen feature branch is detecting LeakSanitizer errors when running the wt3120-filesys & wt2909_checkpoint_integrity csuite tests. We get the following error:

       

      [2021/12/23 06:36:16.411] =================================================================
      [2021/12/23 06:36:16.411] ==132599==ERROR: LeakSanitizer: detected memory leaks

      The above error is due to the CTest invocation of wt3120-filesys & wt2909_checkpoint_integrity passing in a build directory argument (-b). This particular option allocates memory to hold the build directory path string but doesn't free the memory on exit/cleanup.

      Definition of Done:

      • Free the memory backing the build directory argument on testutil_cleanup.
