Currently I see this error in the log:

***************
*** 591,599 ****
  INSERT INTO cstring_table (t)
      VALUES ('thisiscstring');
  SELECT * FROM cstring_table;
!        t
! ---------------
!  thisiscstring
  (1 row)

  DROP TABLE cstring_table;
--- 591,599 ----

  SELECT * FROM cstring_table;

  DROP TABLE cstring_table;

The random bytes in the incorrect result seem to be changing:
