      The timestamp-abort test program has an issue where it reports a failure (missing record) improperly. The failing output looks like:

      This particular output is from http://build.wiredtiger.com:8080/job/wiredtiger-valgrind/2504/console

      This is a test program issue. It didn't read a stable timestamp from the stable ts table for thread 2 and used an uninitialized value instead and therefore reported an error.
