  New Revision: 60720

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=60720

  Log:
    parse.y: fix r60644
    
    * parse.y (rb_strterm_heredoc_t): should not define sourceline as
      union, to fix wrong read on big-endian platforms.
      as rb_imemo_new stores all members as VALUEs, should read it as
      VALUE too.
