re PR libfortran/56737 (Wrong I/O result with format cache for Hollerith strings) 

2013-03-29  Tobias Burnus  <burnus@net-b.de>

        PR fortran/56737
        * io/format.c (parse_format): With caching, copy
        dtp->format string.
        (save_parsed_format): Use dtp->format directy without
        copying.
