  New Revision: 43887

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=43887

  Log:
    * string.c (rb_fstring): fstrings should be ELTS_SHARED.
      If we resurrect dying objects (non-marked, but not swept yet),
      pointing shared string can be collected.
      To avoid such issue, fstrings (recorded to fstring_table)
      should not be ELTS_SHARED (should not have a shared string).
