      Description

      There's a LSM memory leak detected by ASAN while running test/format in the clang sanitizer job on margay-aws

      http://build.wiredtiger.com:8080/job/wiredtiger-clang-sanitizer/3748/console

      ==17581==ERROR: LeakSanitizer: detected memory leaks
       
      Direct leak of 464 byte(s) in 1 object(s) allocated from:
