        PR fortran/18923
        * parse.c (decode_statement): Don't call gfc_undo_symbols on
MATCH_ERROR
        for ST_FUNCTION since it is called in reject_statement.
        (parse_contained): If error, loop back after reject_statement and try
        again.  Free the namespace if an error occured.
