    PR libgfortran/65089
    * io/format.h (free_format): New function to free memory
    allocated for building format error messages.
    * io/format.c (format_error): Add checks before freeing memory
    to avoid potential segfaults and free formatting data when
    needed on error conditions. Always allocate and NULL terminate
    the string.
    * io/transfer.c (st_read_done, st_write_done): Use new
    free_format function to clean up memory allocations when done.
