Bison 1.875 Bug & Fix

Take a look at "parse-gram.y" line 399:

399:      epilogue_augment ($2, @2);
      scanner_last_string_free ();

Since "EPILOGUE" is a fabrication there is no line & file information
associated with it, so @2.file is garbage and causes a core dump (at
least on Windows XP). I think the correct code should look like:

      epilogue_augment ($2, @1);

Thereby referring to the location of "%%".
